NAME
mdoc - Mono Documentation XML Format
DESCRIPTION
The assorted Mono documentation programs generate or manipulate XML files following the
mono documentation schema:
mdoc update
Creates or updates mono documentation XML for a set of assemblies.
mdoc validate
Validates the mono documentation XML against the mono documentation XML schema.
mdoc assemble
Converts the mono documentation XML within a directory structure into a set of
files for use with monodoc(1).
mdoc export-html
Converts the mono documentation XML within a directory structure into a set of HTML
files that can be viewed with a web browser.
All of these tools (and more) use the common XML schema described in this man page.
FILE/DIRECTORY STRUCTURE
There are three sets of Mono documentation XML files:
* index.xml: contains a list of all assemblies within the containing directory, and
all types and namespaces within those assemblies.
* ns-*.xml: There is one ns-*.xml file for each namespace within the assembly; these
files are siblings to index.xml .
Examples of ns-*.xml files include: ns-System.xml, ns-System.Collections.xml, and
ns-.xml (for the root namespace, though it is recommended to NOT place types into
the root namespace, as monodoc(1) doesn't display them).
The ns-*.xml files contain per-namespace documentation.
* NamespaceName/TypeName.xml: These files are within a dotted NamespaceName
directory, and TypeName is the name of the type.
Examples include: RootType.xml (if the type has no namespace), System/String.xml,
System.Collections/IEnumerable.xml, and
System.Collections.Generic/List`1+Enumerator.xml (the `1 is the number of generic
type parameters the type accepts, and everything after the + is a nested type).
Thus, typical directory contents would resemble:
index.xml
ns-System.xml
ns-System.Collections.Generic.xml
System/String.xml
System.Collections.Generic/List`1.xml
DOCUMENTATION FORMAT
index.xml File Format
The index.xml file contains a list of the assemblies nested under the directory containing
index.xml and all namespaces and types within those assemblies. It looks something like
this:
<Overview>
<Assemblies>
<Assembly Name="mscorlib" Version="2.0.0.0" />
<!-- other <Assembly/> elements... -->
</Assemblies>
<Remarks>To be added.</Remarks>
<Copyright>To be added.</Copyright>
<Types>
<Namespace Name="System">
<Type Name="String" />
<!-- Other <Type/> elements -->
</Namespace>
<Namespace Name="System.Collections.Generic">
<Type Name="List`1" DisplayName="List<T>" />
<!-- Other <Type/> elements -->
</Namespace>
<!-- other <Namespace/> elements -->
</Types>
<Title>DocTest</Title>
</Overview>
Most of this is maintained automatically, in particular the /Overview/Assemblies and
/Overview/Types elements.
The //Namespace/@Name attribute corresponds to a directory which contains files named
//Type/@Name.xml, while the //Type/@DisplayName attribute contains a C# type name (if
//Type/@DisplayName isn't found, then //Type/@Name is used as the display name). There
should also be a ns-[//Namespace/@Name].xml file.
There are three elements of interest to authors: /Overview/Remarks, /Overview/Copyright,
and /Overview/Title, which contain assembly-level documentation. These elements can
contain any of the following XML elements (documented in the Documentation XML Elements
section): block, code, example, list, para, paramref, typeparamref, see, and ul.
ns-*.xml File Format
The ns-*.xml files contain namespace documentation:
<Namespace Name="System">
<Docs>
<summary>To be added.</summary>
<remarks>To be added.</remarks>
</Docs>
</Namespace>
The /Namespace/Docs/summary and /Namespace/Docs/remarks elements should contain namespace
documentation.
The remarks and summary elements are documented in the Documentation XML Elements section.
NamespaceName/TypeName.xml File Format
The mono documentation format is similar to the Ecma documentation format, as described in
ECMA-335 3rd Edition, Partition IV, Chapter 7. The principal difference from the ECMA
format is that each type gets its own file, within a directory identical to the namespace
of the type. There is a lot of information that is maintained automatically by mdoc(1);
Most of the information within the documentation should not be edited. This includes the
type name (/Type/@FullName), implemented interfaces (/Type/Interfaces), member information
(/Type/Members/Member/@MemberName, /Type/Members/Member/MemberSignature,
/Type/Members/Member/MemberType, /Type/Members/Member/Parameters, etc.).

<Docs>
<param name="docs">To be added.</param>
<summary>To be added.</summary>
<remarks>To be added.</remarks>
</Docs>
</Member>
</Members>
</Type>
The only elements that normally need to be edited are children of the //Docs elements,
which usually contain the text To be added. The /Type/Docs element contains type-level
documentation, while the /Type/Members/Member/Docs element contains per-member
documentation.
The //Docs elements can contain the following elements: altcompliant, altmember, example,
exception, param, permission, remarks, returns, since, summary, threadsafe, typeparam, and
value.
Nested types are not members; they are types, and are documented in their own file.
Consequently, the NamespaceName/TypeName.xml files are not recursive; you do not store a
<Type/> element within a <Type/> element.
Documentation XML Elements
The contents of the Docs element is identical in semantics and structure to the inline C#
documentation format, consisting of these elements (listed in ECMA-334 3rd Edition, Annex
E, Section 2). The following are used within the element descriptions:
CREF Refers to a class (or member) reference, and is a string in the format described
below in the CREF FORMAT section.
TEXT Non-XML text, and XML should not be nested.
XML Only XML elements should be nested (which indirectly may contain text), but non-
whitespace text should not be an immediate child node.
XML_TEXT
Free-form text and XML, so that other XML elements may be nested.
The following elements are used in documentation:
<altmember cref="CREF" />
<altmember/> is a top-level element, and should be nested directly under the
<Docs/> element.
Allows an entry to be generated for the See Also section. Use <see/> to specify a
link from within text.
<altmember cref="P:System.Exception.Message" />
<block subset="SUBSET" type="TYPE">XML_TEXT</block>
Create a block of text, similar in concept to a paragraph, but is used to create
divisions within the text. To some extent, a <block/> is equivalent to the HTML
<h2/> tag.
SUBSET should always be the value "none".
TYPE specifies the heading and formatting to use. Recognized types are:
behaviors Creates a section with the heading Operation.
note Creates a section with the heading Note:.
overrides Creates a section with the heading Note to Inheritors.
usage Creates a section with the heading Usage.
The block element can contain the following elements: block, c, code, list, para,
paramref, see, subscript, sup, and typeparamref.
<c>XML_TEXT</c>
Set text in a code-like font (similar to the HTML <tt/> element).
The c element can contain the following elements: code, para, paramref, see, and
typeparamref.
<code lang="LANGUAGE" src="SOURCE">TEXT</code>
Display multiple lines of text in a code-like font (similar to the HTML <pre/>
element).
LANGUAGE is the language this code block is for. For example, if LANGUAGE is C#,
then TEXT will get syntax highlighting for the C# language within the Mono
Documentation Browser.
SOURCE is only interpreted by mdoc-update(1). If the src attribute is present when
mdoc-update(1) is run, then SOURCE is a file (relative to mdoc-update(1)'s --out
directory) that should be inserted as the value for TEXT. The contents of TEXT
will be ignored by mdoc-update(1) and replaced on every invocation. SOURCE can
also contain an "anchor", e.g. src="path/to/file.cs#RegionMarker". If an anchor is
present, and LANGUAGE is C#, then #region RegionMarker will be searched for, and
the contents between the #region and the following #endregion will be inserted as
the value for TEXT element.
<example>XML_TEXT</example>
Indicates an example that should be displayed specially. For example:
<example>
<para>An introductory paragraph.</para>
<code lang="C#">
class Example {
public static void Main ()
{
System.Console.WriteLine ("Hello, World!");
}
}
</code>
</example>
The example element can contain the following elements: c, code, list, para, and
see.
<exception cref="CREF">XML_TEXT</exception>
Identifies an exception that can be thrown by the documented member.
<exception/> is a top-level element, and should be nested directly under the
<Docs/> element.
CREF is the exception type that is thrown, while XML_TEXT contains the
circumstances that would cause CREF to be thrown.
<exception cref="T:System.ArgumentNullException">
<paramref name="foo" /> was <see langword="null" />.
</exception>
The exception element can contain the following elements: block, para, paramref,
see, and typeparamref.
<format type="TYPE">XML_TEXT</format>
The <format/> element is an "escape hatch," for including (possibly XML) content
that is not valid mdoc(5) content. It's the moral equivalent of perlpod(1) =begin
format blocks.
TYPE is the mime type of XML_TEXT. mdoc(5) processors may skip format/> blocks of
they use a type that isn't supported.
For example:
<format type="text/html">
<table width="100%">
<tr><td style="color:red">Hello, world!</td></tr>
</table>
</format>
would cause the embedded HTML <table/> element to be inserted inline into the
resulting HTML document when mdoc-export-html(1) processes the file. (Likewise, it
may be skipped if processed by another program.)
format/> is intended to simplify importing documentation from existing
documentation sources. It should not be relied upon, if at all possible.
<list>XML</list>
Create a list or table of items. <list/> makes use of nested <item>XML</item>,
<listheader>XML</listheader>, <term>XML_TEXT</term>, and
<description>XML_TEXT</description> elements.
Lists have the syntax:
<list type="bullet"> <!-- or type="number" -->
<item><term>Bullet 1</term></item>
<item><term>Bullet 2</term></item>
<item><term>Bullet 3</term></item>
</list>
Tables have the syntax:
<list type="table">
<listheader> <!-- listheader bolds this row -->
<term>Column 1</term>
<description>Column 2</description>
<description>Column 3</description>
</listheader>
<item>
<term>Item 1-A</term>
<description>Item 1-B</description>
<description>Item 1-C</description>
</item>
<item>
<term>Item 2-A</term>
<description>Item 2-B</description>
<description>Item 2-C</description>
</item>
</list>
The item and description elements can each contain text and the following elements:
block, c, para, paramref, see, sup, and typeparamref.
<para>XML_TEXT</para>
Insert a paragraph of XML_TEXT. For example,
<para>
This is a paragraph of text.
</para>
The para element can contain the following elements: block, c, example, link, list,
onequarter, paramref, see, sub, sup, typeparamref, and ul.
<param name="NAME">XML_TEXT</param>
<param/> is a top-level element, and should be nested directly under the <Docs/>
element.
Describes the parameter NAME of the current constructor, method, or property:
<param name="count">
A <see cref="T:System.Int32" /> containing the number
of widgets to process.
</param>
The param element can contain the following elements: block, c, example, para,
paramref, see, and typeparamref.
<paramref name="NAME" />
Indicates that NAME is a parameter.
This usually renders NAME as italic text, so it is frequently (ab)used as an
equivalent to the HTML <i/> element. See the <exception/> documentation (above)
for an example.
<permission cref="CREF">XML_TEXT</permission>
Documents the security accessibility requirements of the current member.
<permission/> is a top-level element, and should be nested directly under the
<Docs/> element.
CREF is a type reference to the security permission required, while XML_TEXT is a
description of why the permission is required.
<permission cref="T:System.Security.Permissions.FileIOPermission">
Requires permission for reading and writing files. See
<see cref="F:System.Security.Permissions.FileIOPermissionAccess.Read" />,
<see cref="F:System.Security.Permissions.FileIOPermissionAccess.Write" />.
</permission>
The permission element can contain the following elements: block, para, paramref,
see, and typeparamref.
<remarks>XML_TEXT</remarks>
Contains detailed information about a member.
<remarks/> is a top-level element, and should be nested directly under the <Docs/>
element.
<remarks>
Insert detailed information here.
</remarks>
The remarks element can contain the following elements: block, c, code, example,
list, para, paramref, see, and typeparamref.
<returns>XML_TEXT</returns>
<returns/> is a top-level element, and should be nested directly under the <Docs/>
element.
Describes the return value of a method:
<returns>
A <see cref="T:System.Boolean" /> specifying whether
or not the process can access
<see cref="P:Mono.Unix.UnixFileSystemInfo.FullName" />.
</returns>
The returns element can contain the following elements: c, format, list, para,
paramref, see, and typeparamref.
<see cref="CREF" />, <see langword="LANGWORD" />
Creates a link to the specified member within the current text:
<see cref="M:Some.Namespace.With.Type.Method" />
or specifies that LANGWORD is a language keyword:
<see langword="null" />
<seealso cref="CREF" />
Do not use seealso, use altmember.
<since version="VERSION" />
<since/> is a top-level element, and should be nested directly under the <Docs/>
element.
Permits specification of which version introduced the specified type or member.
<since version="Gtk# 2.4" />
This generally isn't required, as the //AssemblyInfo/AssemblyVersion elements track
which assembly versions contain type or member.
<summary>XML_TEXT</summary>
<summary/> is a top-level element, and should be nested directly under the <Docs/>
element.
Provides a (brief!) overview about a type or type member.
This is usually displayed as part of a class declaration, and should be a
reasonably short description of the type/member. Use <remarks/> for more detailed
information.
The summary element can contain the following elements: block, list, para,
paramref, see, and typeparamref.
<typeparam name="NAME">XML_TEXT</typeparam>
<typeparam/> is a top-level element, and should be nested directly under the
<Docs/> element.
This is used to document a type parameter for a generic type or generic method.
NAME is the name of the type parameter, while XML_TEXT contains a description of
the parameter (what it's used for, what restrictions it must meet, etc.).
<typeparam name="T">
The type of the underlying collection
</typeparam>
The typeparam element can contain the following elements: block, c, para, paramref,
see, and typeparamref.
<typeparamref name="NAME">
Used to indicate that NAME is a type parameter.
<value>XML_TEXT</value>
<value/> is a top-level element, and should be nested directly under the <Docs/>
element.
Allows a property to be described.
<value>
A <see cref="T:System.String" /> containing a widget name.
</value>
The value element can contain the following elements: block, c, example, list,
para, paramref, see, and typeparamref.
CREF FORMAT
String IDs (CREFs) are used to refer to a type or member of a type. String IDs are
documented in ECMA-334 3rd Edition, Annex E.3.1. They consist of a member type prefix,
the full type name (namespace + name, separated by .), possibly followed by the member
name and other information.
Member type prefixes:
C: The CREF refers to a constructor. The (optional) parameter list is enclosed in
parenthesis and follows the type name: C:System.String(System.Char,System.Int32).
E: The CREF refers to an event. The event name follows the type name:
E:System.AppDomain.AssemblyLoad.
F: The CREF refers to a field. The field name follows the type name:
F:System.Runtime.InteropServices.DllImportAttribute.SetLastError.
M: Refers to a constructor or method. Constructors may append .ctor to the type name
(instead of using the above C: constructor format), while methods append the method
name and an (optional) count of the number of generic parameters. Both
constructors and methods may append the method parameter list enclosed in
parenthesis.
Examples: M:System.Object..ctor, M:System.String..ctor(System.Char[]),
M:System.String.Concat(System.Object), M:System.Array.Sort``1(``0[]),
M:System.Collections.Generic.List`1..ctor,
M:System.Collections.Generic.List`1.Add(`0).
N: Refers to a namespace, e.g. N:System.
P: Refers to a property. If the property is an indexer or takes parameters, the
parameter types are appended to the property name and enclosed with paranthesis:
P:System.String.Length, P:System.String.Chars(System.Int32).
T: The CREF refers to a type, with the number of generic types appended:
T:System.String, T:System.Collections.Generic.List`1,
T:System.Collections.Generic.List`1.Enumerator.
To make matters more interesting, generic types & members have two representations: the
"unbound" representation (shown in examples above), in which class names have the count of
generic parameters appended to their name. There is also a "bound" representation, in
which the binding of generic parameters is listed within '{' and '}' or '<' and '>'. (Use
of '<' and '>' is less common, as within an XML document their escaped character entities
must instead be used, leading to '<' and '>'.)
Unbound:
* T:System.Collections.Generic.List`1
* T:System.Collections.Generic.Dictionary`2
Bound:
* T:System.Collections.Generic.List{System.Int32}
* T:System.Collections.Generic.List<System.Int32>
* T:System.Collections.Generic.List<System.Int32>
* T:System.Predicate{System.Action{System.String}}
As you can see, bound variants can be arbitrarily complex (just like generics).
Furthermore, if a generic parameter is bound to the generic parameter of a type or method,
the "index" of the type/method's generic parameter is used as the binding, so given
class FooType {
public static void Foo<T> (System.Predicate<T> predicate)
{
}
}
The CREF for this method is M:FooType.Foo``1(System.Predicate{``0}), ``0 is the 0th
generic parameter index which is bound to System.Predicate<T>.
