What does "resolvable" mean in a technical sense though?  Isn't
"resolvable" in openid simply a set of rules that converts a URI into
an XRDS / Yadis document?  How is a set of rules that maps an e-mail
URI to an XRDS / Yadis document any different from the sets of rules
that maps an xri URI or even the http / https URIs to a XRDS / Yadis

David has a proposal that with a slight tweak would make e-mail URI's
directly "resolvable" to an XRDS / Yadis document. Isn't that in line
with your definition?
