Dave, please don't confuse the schema modelling language with the editor
used for the instance. RNG/C is unquestionably the best tool for
modelling schemas, complex or otherwise.

But it isn't supported yet by enough editors, and — critically — IFF
your model does not require schema-like features like hard datatyping,
there should be nothing to stop you using a DTD if the editor you prefer
only supports DTDs, and all the features you need can be represented in
a DTD. It's a stopgap.

In an ideal world, nxml would have a proper interface toolset, suitable
for *authors*, and we could then lay DTDs to rest somewhere quiet and
flowery.
