>If an XML vocabulary is large and complex, does that mean it's bad?
The world is large and complex.
If you have a large and complex XML vocabulary, it might be a symptom
that you've bitten off too large a problem and you should tackle
something smaller. Or it might be a symptom that you've failed to find
the right levels of abstraction. (Though I think some XML vocabularies -
XBRL and HL7 come to mind - suffer from being too abstract.) In general
though, it might just indicate that you're tackling a large and complex
problem.
It would be a brave person who claimed that GML is too large and
complex, for example. Given the problem they have chosen to tackle,
which bits would you leave out?
