       Extends "Collections" in User::Identity::Item.

       $obj->addCollection(OBJECT | ([TYPE], OPTIONS))
           Inherited, see "Collections" in User::Identity::Item

       $obj->collection(NAME)
           Inherited, see "Collections" in User::Identity::Item

       $obj->find(COLLECTION, ROLE)
           Inherited, see "Collections" in User::Identity::Item

       $obj->parent( [PARENT] )
           Inherited, see "Collections" in User::Identity::Item

       $obj->user()

   Access to the archive
       $obj->from(SOURCE, OPTIONS)
           Read definitions from the specified SOURCE, which usually can be a filehandle or
           filename.  The syntax used in the information SOURCE is archiver dependent.

           Not all archivers implement "from()", so you may want to check with "UNIVERSAL::can()"
           beforehand.

           example:

            use User::Identity::Archive::Some;
            my $a = User::Identity::Archive::Some->new('xyz');
            $a->from(\*STDIN) if $a->can('from');

DIAGNOSTICS

       Error: $object is not a collection.
           The first argument is an object, but not of a class which extends
           User::Identity::Collection.

       Error: Cannot load collection module for $type ($class).
           Either the specified $type does not exist, or that module named $class returns
           compilation errors.  If the type as specified in the warning is not the name of a
           package, you specified a nickname which was not defined.  Maybe you forgot the
           'require' the package which defines the nickname.

       Error: Creation of a collection via $class failed.
           The $class did compile, but it was not possible to create an object of that class
           using the options you specified.

       Error: Don't know what type of collection you want to add.
           If you add a collection, it must either by a collection object or a list of options
           which can be used to create a collection object.  In the latter case, the type of
           collection must be specified.

       Warning: No collection $name
           The collection with $name does not exist and can not be created.
