The problem are the conformance requirements implied by "allowable". If
you develop a URI Validator and add support for the 'jabber' scheme, it
is not clear whether strings like "JABBER:client" or "jabber:%63lient", 
or even "jabber:client#" should be rejected. These strings are not on
the list of "allowable" strings, so some will argue they ought to be re-
jected, while others will argue per RFC 3986 they ought to be accepted.
