		<description>+1 to using hCard/vCard.

Totally agree - don't need yet-another-schema.

Having built several webapps in the last few years that store identity data, I've found using the vCard schema all the way down to the database layer very effective.

Schema reuse is just as powerful as code reuse.</description>

		<description>How do you propose the relying party get the hCard?  As a payload in the OpenID response, alongside the signature, and signed?

If not, then as discovery?  (fetching the public URL)  In that case, how do you deal with non-public information?

I'm not disagreeing with anything you said; just curious how you see this working.</description>

		<description>Hmm.  How would this cope with the need to provide different attributes to (and, more importantly, to EXCLUDE different attributes from) different sites/services?</description>
