There's no need to eliminate <dc:date> -- I'm pretty sure
it's okay for a feed to have both a <dc:date> and a <pubDate>.
This would hit a wider variety of readers.

I've gone ahead and updated feeds.php to include <pubDate> in
rss feeds.  The new version is attached, and will be in the
beta21 release.

    This script provides a number of syndication feed and xml-based 
    metadata options to PmWiki, including Atom, RSS 2.0, RSS 1.0 (RDF), 
    and the Dublin Core Metadata extensions.  This module is typically
    activated from a local configuration file via a line such as

      if ($action == 'atom') include_once("$FarmD/scripts/feeds.php");
      if ($action == 'dc') include_once("$FarmD/scripts/feeds.php");

    When enabled, ?action=atom, ?action=rss, and ?action=rdf produce
    syndication feeds based on any wikitrail contained in the page,
    or, for Category pages, on the pages in the category.  The feeds
    are generated using pagelist, thus one can include parameters such
    as count=, list=, order=, etc. in the url to adjust the feed output.

    ?action=dc will normally generate Dublin Core Metadata for the 
    current page only, but placing a group=, trail=, or link= argument 
    in the url causes it to generate metadata for all pages in the
    associated group, trail, or backlink.

    There are a large number of customizations available, most of which
    are controlled by the $FeedFmt array.  Elements $FeedFmt look like

        $FeedFmt['atom']['feed']['rights'] = 'All Rights Reserved';

    where the first index corresponds to the action (?action=atom),
    the second index indicates a per-feed or per-item element, and
    the third index is the name of the element being generated.
    The above setting would therefore generate a
    "<rights>All Rights Reserved</rights>" in the feed for
    ?action=atom.  If the value of an entry begins with a '<',
    then feeds.php doesn't automatically add the tag around it.
    Elements can also be callable functions which are called to
    generate the appropriate output.

    Feeds.php can also be combined with attachments to support
    podcasting via ?action=rss.  Any page such as "PageName"
    that has an mp3 attachment with the same name as the page
    ("PageName.mp3") will have an appropriate <enclosure> element
    in the feed output.  The set of allowed attachments can be
    extended using the $RSSEnclosureFmt array:

        $RSSEnclosureFmt = array('{$Name}.mp3', '{$Name}.mp4');
