RE: DTD and Illegal Construct

I believe even (A|A?) or (A|A) is invalid (non-deterministic), and it
doesn't matter what the model after each A is.

Honestly, I'm not playing stump the experts, but what about the instance?

((A, B, D?) | (A?, B, C?, D?, E))

In this instance 'C' can only be present if 'E' is present.
