       EPP is the Extensible Provisioning Protocol. EPP (defined in RFC 4930) is an application
       layer client-server protocol for the provisioning and management of objects stored in a
       shared central repository. Specified in XML, the protocol defines generic object
       management operations and an extensible framework that maps protocol operations to
       objects. As of writing, its only well-developed application is the provisioning of
       Internet domain names, hosts, and related contact details.

       EPP uses XML documents called "frames" send data to and from clients and servers. This
       module implements a subclass of the XML::LibXML::Document module that simplifies the
       process of creation of these frames. It is designed to be used alongside the
       Net::EPP::Client module.




       As a rule, you will not need to create Net::EPP::Frame objects directly.  Instead, you
       should use one of the subclasses included with the distribution.  The subclasses all
       inherit from Net::EPP::Frame.

       Net::EPP::Frame is itself a subclass of XML::LibXML::Document so all the methods available
       from that class are also available to instances of Net::EPP::Frame.

       The available subclasses of Net::EPP::Frame exist to add any additional elements required
       by the EPP specification. For example, the <login> frame must contain the <clID> and <pw>
       frames, so when you create a new Net::EPP::Frame::Command::Login object, you get these
       already defined.

       These classes also have convenience methods, so for the above example, you can call the
       "$login->clID" and "$login->pw" methods to get the XML::LibXML::Node objects
       correesponding to those elements.

       You could just as easily construct your EPP frames from templates or just lots of
       "printf()" calls. But using a programmatic approach such as this strongly couples the
       validity of your XML to the validity of your program. If the process by which your XML is
       built is broken, your program won't run. This has to be a win.


               my $str = $frame->formatTimeStamp($timestamp);

       This method returns a scalar in the required format (defined in RFC 3339). This is a
       convenience method.

               my $node = $frame->getNode($id);
               my $node = $frame->getNode($ns, $id);

       This is another convenience method. It uses $id with the getElementsByTagName() method to
       get a list of nodes with that element name, and simply returns the first
       XML::LibXML::Element from the list.

       If $ns is provided, then getElementsByTagNameNS() is used.

               my $binary = $frame->header;

       Returns a scalar containing the frame length packed into binary. This is only useful for
       low-level protocol stuff.

               my $data = $frame->frame;

       Returns a scalar containing the frame header (see the header() method above) concatenated
       with the XML frame itself. This is only useful for low-level protocol stuff.


       Net::EPP::Frame, the base class
       Net::EPP::Frame::Command, for EPP client command frames
       Net::EPP::Frame::Command::Check, for EPP <check> client commands
       Net::EPP::Frame::Command::Create, for EPP <create> client commands
       Net::EPP::Frame::Command::Delete, for EPP <delete> client commands
       Net::EPP::Frame::Command::Info, for EPP <info> client commands
       Net::EPP::Frame::Command::Login, for EPP <login> client commands
       Net::EPP::Frame::Command::Logout, for EPP <logout> client commands
       Net::EPP::Frame::Command::Poll, for EPP <poll> client commands
       Net::EPP::Frame::Command::Renew, for EPP <renew> client commands
       Net::EPP::Frame::Command::Transfer, for EPP <transfer> client commands
       Net::EPP::Frame::Command::Update, for <update> client commands
       Net::EPP::Frame::Greeting, for EPP server greetings
       Net::EPP::Frame::Hello, for EPP client greetings
       Net::EPP::Frame::Response, for EPP server response frames

       Each subclass has its own subclasses for various objects, for example
       Net::EPP::Frame::Command::Check::Domain creates "<check>" frame for domain names.

       Coverage for all combinations of command and object type is not complete, but work is
