[OpenID] W3C TAG recommends against XRI

[Andrew Arnott]

Since the introduction of use of XRIs in the OpenID and extension specs,
I've been confused when URI is used in the spec in knowing whether this had
to be a standard-looking http: URL or if an XRI is an acceptable URI.  Is
XRI a specific type of the more general URI?

One specific instance of confusion for me is in Attribute
Exchange<http://openid.net/specs/openid-attribute-exchange-1_0.html#attribute-name-definition>spec
where it discusses the attribute type URI.  Must this be a valid http:
URL, or can it be an XRI or some other string format?

Thanks.
