Right, the examples I gave there are the actual files; that is the
post-0.6 AppStream version which only works with Fedora > 20.

Right, those are AppData files for applications, not MetaInfo files
for fonts and addons. When F20 is EOL I'll update that page to the new
metadata format.

Right; you need to use a metainfo file and a git version of
appstream-glib to validate those. I only wrote the code 6 hours ago :)

Not appdata.xml, but metainfo.xml -- This is the patch I want to apply for lato:
