One of the requirements in the JRD spec is that certain URIs (e.g., those
identifying link relation types and properties) be "absolute URIs".  This
term has been a point of confusion, since RFC 3986 uses the term to have a
concrete meaning, namely this:

     absolute-URI  = scheme ":" hier-part [ "?" query ]

And the term is used, because that's the term used in the OASIS XRD
specification.  However, it was not clear to me whether that referred to the
above (which I assumed) or referred to URIs that are not relative URIs
(i.e., those lacking a scheme specified).

I had an exchange with Eran Hammer and Mark Nottingham.  I believe the
intent of that language was not to require the above constrained syntax,
but to require the standard URI syntax:

     URI = scheme ":" hier-part [ "?" query ] [ "#" fragment ]

Given that understanding, I believe we should remove the word "absolute"
that appears in front of "URI" in the WebFinger spec.  Do others have an
opinion on this?
