I think the canonical form is "text/xml", and yes, the skin is
already setting the http header.

Okay, you're asking for something very different from what PmWiki
produces.  PmWiki doesn't have markup rules for producing <link>
elements, or things like <PmWikiXML>, or placing things inside of
CDATA contexts.  We could possibly create such markups, but that's
quite a bit more complex than a simple skin would typically
provide.

It seems that what you're really looking for is something more
along the lines of an RSS feed, which _does_ generate XML output
directly from pagelists.  And feeds.php is fully configurable, 
meaning it's possible to define custom tags and components in 
the XML output.
