Standard? In what way? RFC 3470 "Guidelines for the Use of Extensible
Markup Language (XML) within IETF Protocols" does not give it any
special status. Some RFC use W3C XML Schema (RFC 4931), some use
another schema langage (RFC 4287).

Even at its birthplace of W3C, they now use Relax NG for some
standards (http://www.w3.org/TR/SVG12/).

Sorry, as you say, you are not a guru. One can say many things about
the strengths and weaknesses of the various XML schema languages but I
believe that there is a clear consensus that Relax NG is by far the
most powerful.

This is not possible for the recordjar2anything converters because the
information is not, unfortunately, in the registry.
