Content model probs

> 1. Contain #PCDATA, *OR*

Can't be done.  Content models that include #PCDATA and elements are
restricted to the form (#PCDATA|x|y|...)*.

> At the moment I've had to settle on (#PCDATA|X|Y)*

Yes, that's the best you can do.

If you want to do better, you will need to have two different element
types for the two cases.
