Sorry, am rather distracted today with a ton of things, so no doubt
missed some nuance.  I've also not come across any examples where
"levels" are particularly meaningful in citations, so conveniently
passed that over ;-)

However, in any case, I do think we need to find a simpler example
than your "simple" example.  One thing I have come around to over the
past bit of time is that it's essential that our metadata models and
formats be easier to work with for non-experts; both those who would
create the metadata, and those who would write tools to consume it. 
It's hard enough to convince people to even do decent DC.

I realize my example is problamatic because I use the term "number"
when we could be talking about, say, <ex:part>B</ex:part>.  But could
you imagine achieving the same effect without having to use terms like
"levels" or "enumerations"?  Even if different journals were to use
"part" inconsistently, does it really matter, either for citations, or
for finding the correct item?

BTW, in RDF, one tends to takea a different tack than this approach of
having generic metadata structures (say "enumeration"), with specific
modifiers (a type attribute).  Instead, one would define specific
structures, and then if you need to say that, for example, volume and
issue are both kinds of enumerations, one would define that in the
ontology (above the XML in effect).
