validating microformats (was Re: [uf-discuss] Google Gdata new syndication protocol!)

[Luke Arno]

Mark P. is on the right track here as usual, I think.

What has been glossed over in this convo is that
underlying the discomfort that has been expressed
on the validation front here is this:

Sure you can validate a microformat reasonably
well (though it may be difficult to validate format
transformations that result in microformats) but
there is not meta-microformat (god, did I just say
that?!?) to conduct validation automatically
(ie without manually translating the spec into
rules that your validator can understand) We
have profiles, of course but they are not machine
readable like a schema for tower of babel XML
(XSD or RNG or what not).

I agree with the previous comment that schematron
is probably the most promising alternative for uf.
