Log Message:
Update p5-XML-Atom to 0.23, mostly as provided by Martin Wilke in
PR pkg/34420.

Revision history for XML::Atom:

0.23  2006.08.27
    * Fixed the method to get xml:lang and xml:base due to the
      XML::LibXML 1.60 change which invalidated it.

0.22  2006.07.24
    * Refactored internal element accessors by eating the new dog food
      mk_elem_accessors and mk_object_list_accessor.
    * Added support of Atom 1.0 <category> parse and generation
    * Added $thing->links and $thing->categories as a moniker method
      that returns an array reference in a scalar context
    * Fixed a bug in $content->body() where it accidentally thinks the
      content is not a valid Unicode string even if it is, if you call
      eval {} in elsewhere in the code and $@ is left set.
      (Thanks to Chris Dent for the patch)

0.21  2006.07.13
    * propagate $entry's version when we create content element off of entry
      using $entry->content("foo") syntax.
      (Thanks to Simon Wistow for spotting this bug)

0.20  2006.07.12
    * Lots of refactoring, which simplifies much of the code in the various
      construct modules (Person, Link, etc), and which should also make it
      much more straightforward to add extension classes in the future.
    * Added global $XML::Atom::ForceUnicode flag to return everything as Unicode \ 
flagged
      (Suggested by many people)
    * Added global $XML::Atom::DefaultVersion flag to set default
      version number for generated Atom feed. Defaults to 0.3 (for backward \ 
compatibility)
    * Added support for atom:content @type in Atom 1.0 feeds
      (Suggested by many people, especially Chris Dent and Andy Lester from \ 
Socialtext)

0.19  2006.03.19
    * Fix 0.18 bug where renaming stuff was totally broken.

0.18  2006.03.16
    * Support Atom 0.3 -> 1.0 renaming bits (issued -> published,
      modified -> updated, tagline -> subtitle)
    * $atom->content->body doesn't return Unicode flagged variable
      anymore, even if it's text/ data. Now it just returns UTF-8 bytes.
      (Thanks to Garth Webb)
