I finally found the test suite (a great resource, BTW) and validated the
test cases against my schemas. There was one bug in the schemas (forgot
the "identifier" element in "attribution") and a few things I'm not sure
about:
Both schemas accepted fail/playlist-badversion.xspf, because I checked
for "\d+" in the version attribute. I decided to hardcode it to "1" for
now.
The Relax NG schema also accepts fail/playlist-noturi-info.xspf and
fail/track-noturi-info.xspf, which is a moot point. The string
"This should be a URI" could be a relative URI with unencoded spaces.
This is valid according to [1], but discouraged.
Anyway, an updated revision of the schemas is attached to this mail.
Cheers,
Matthias
