I like Mireille's suggestion, but I think we don't need a name space.
The "thing in front of the colon" in utypes is, according to the
current utype proposal, *not* a name space in the XML sense (but
rather a model identifier).  And that's a good thing, because only in
this way you can let people embed literal strings into their programs
and tell them: That's the string to look for when you're trying to
find an error for this particular value.

So, DataModelReference.Uri will do; there are no declared namespaces
in utypes since they are, at least to users, opaque strings.

One qualm, though:  People complain that utype always are so long,
and I tend to agree.  Couldn't we just call the first atom

DataModel

or even just

DM?

Thanks,
