That was my original design. Ron thought it was clearer to allow
an explicit PCData element equivalent to an empty Mixed element,
and I acquiesced.

It *is* "built in", which is why it can sensibly be represented by a
#FIXED attribute. That way, people can see Mixed, Seq, and Choice
as adhering to a common "frequency architecture". Just a thought,
not anything I'm fanatical about.
