I'm certainly not in the position to judge what IANA can or can not do.
However, why wait for IANA to move? We can set up something comparable to
what Ed Summers did for the media types registration [1] at [2].

The IANA has based its registry on XML, AFAICT [3] - so I guess time for
some nice XSLTs ;)

Cheers,
      Michael
