A general point: I am not convinced it's a good idea to make DALI
list all the xtypes we care about, since requiring a DALI update
when inventing an xtype elswhere in the standards landscape
introduces a hurdle that is IMHO unnecessarily painful -
this MOC thing is a case in point.

I agree that a central list of known xtypes is a useful thing to
have, but it could be in a Note outside of the standards process
or even (my vote) a wiki page.
