The qPodder/Nellygator OPML isn't validating (in Dave Winer's OPML validator at validator.opml.org) or displaying in a number of OPML viewers (neither Grazr nor Optimal displays it).

The reason is quite simple - the attributes are wrongly named. The attribute named "url" needs to be named "xmlUrl" instead. You can also put in "htmlUrl" as an attribute. The type needs to be "rss" rather than "link" (link is for inclusion in OPML 1.1 and links to HTML rather than XML resources in OPML 1.1 and 2.0).

This is important as having a validating OPML file means that geeks like me can easily promote all of the qPodder members, future podcatchers that may include "listening list" capabilities will be able to listen to your shows and podcast directories like podcast.com will be able to index and list your shows. I am working on lots of new ways to display this information in new ways and places.

If you would like me to fix it, please feel free to forward the code to me and I can work on it until it produces OPML that validates.
