The Atom feed generated from the Microformats on my home page does not validate.

The first item in the Microformats of my home page is my primary h-card. It's marked up properly with u-url and u-uid matching my home page URL. The rest of the items on the page are h-entrys, and should be converted to Atom entries. The first item however ends up as a mostly empty Atom entry, which breaks some parsers and does not validate either.

I would recommend either dropping all unrecognized items from the generated Atom feed (converting only recognized ones like h-entry), or special-casing this type of situation where a home page feed of posts is not wrapped in an explicit h-feed.
