The entire reason that the +xml suffix was changed from the original
-xml suffix was beczause there were a number of hyphenated types in use
but little/no types where the terms were separated by +.

I agree that so far there are no types with a + in the name, and that
using some other allowed separator would be preferable.

Probably not (I for one would argue against it, being a member of that
group). But 'may include' is pretty weak.

True.
