[OpenID] OpenID Discovery for Email like identifiers - Draft 0.1

[Dirk Balfanz]

In general, I don't think you need to "adapt" webfinger. Webfinger gives you
everything you need. The OpenID community just needs to decide whether the
email-like identifiers falling out of webfinger are acceptable OpenIDs.

Couple of specific comments:
- re signatures: I would just use whatever the XRI TC comes up with there
for XRD signing.
- I don't think you should have the openid21.provider Rel-type with the URI.
Since you start with an email(-like) identifier, it is clear that you're
performing discovery on an identifier for a user, not for a host. So you
should only look for a Link element that has a URITemplate in it. If you
want to map all users to the same endpoint, just make it a template that
doesn't actually have any unbound variables in it.
- "openid21.usermeta" should should be something generic like "describedby"
 - as you point out that's the user's _meta data_, not just OpenID stuff
(although there was some discussion at IIW that "describedby" isn't
appropriate b/c the email-like identifier isn't technically a URI, and
URITemplates, and "describedby" are supposed to be for URIs - but I think
that's a technicality we'll work out).
- the openid21.local_id being its own Link seems weird to me. Why not
something like this:

<Link>
  <Rel>openid.provider</Rel>
  <URI>http://openidprovider.com/op</URI>
  <openid:LocalID xmlns:openid="http://...">some-local-id</openid:LocalID>
</Link>
