Could you point me to details, e.g. a section in that spec?  I would be
interested.

Adoption is a good point.  Otherwise I tend to be opposed against, because the
semantic web works well with URIs only, at least for the, granted, experts who
are currently using it.

But if we were to introduce a name registry for CDs (why not, might be worth
discussing), would be have the resources to do so?  The OpenMath Society does
a good job in acting as a registry for the official CDs, and apparently that
works well enough for MathML to delegate that responsibility to OpenMath.
OTOH there are also private and experimental CDs, with which both OpenMath and
Content MathML should also work, and I'm not sure whether the OpenMath Society
would want to take over the responsibility of registering them as well.  And,
to be honest, we have to admit that the OpenMath Society does not currently
have that much work to do about maintaining and registering CDs, as for the
average user the mechanism of submitting a CD is rather obscure (a problem
criticised at the OpenMath business meeting, which will be improved).

Cheers,

Christoph
