I have to ask, though, is that section written precisely or not? I take it
as meaning this:
For compatibility, it is an error if an element in A document COULD
match
more than one occurrence of an element type in the content model."
If this is the correct reading, then the non-deterministic evaluation is
made across the set of all possible documents, not just the instance
document in question. To me, this makes much more sense, since the
acceptablility of a content model is decoupled from any one instance.
Does anyone definitely know whether this is just an editorial issue (my
reading) or whether Rob's reading is what was intended?
