Sorry I am just a lame-oh user-level kinda guy so if my description of the problem needs clarification, let me know. Example:
http://literalsystems.com/abooks/feed.php?mode=list&ns=audio (a mode to list every page in this namespace) puts out ugly formatted results, and not the nice looking page heading names that one gets with a similar goal of
http://literalsystems.com/abooks/feed.php?ns=audio&num=1000. I don't know what else to add here, except I am generating RSS2 feeds if that helps.
Bzzz. Sounds like a bug to me. ;-)
