you can always use XInclude if you want. The point of the key= mechanism
is that it does _not_ point to a URL, because the material may come
from a database query, or some local file, or anything; we don't
want to commit an ODD to the method used to locate the P5 source

true. I wish I thought cascading odds genuinely worked.

you _could_ use <moduleRef url="...."> instead of @key, but thats
rather under-implemented. I'd have to do some work to make that
behave properly.

well, that would need some playing around with to get right. the "tei" 
module
is genuine and must be read.

hmm. I think so

I'd have to experiment with this to see what I have actually 
implemented. I may well
have got it wrong, and so broken cascades.

part of the output of P5 is a set of DTD and RELAXNG modules, which
can be included in your own schema using native tools (such as RELAXNG's
<include>)
