  | That's fine by me, except that it would need to be:
  | xml/x-myml
  | xml/x-theirml
  | xml/x-everyonesml (or xml/everyonesml if 'everyonesml' was a registered
  | subtype.)

OK, that's fine.

But to rephrase my question:

Who decides which DTDs have sufficient merit/useage/stability/etc
to warrant a registered subtype?

It seems unrealistic to expect IETF to make those sort
of decisions.

Or, to rephrase again:

If I write a new DTD for (say) classifying house bricks,
to be used in the building industry, and I go to to the
IETF, and say:

	Give me a registered subtype!

What should they do and say?
