I am trying to match the XSD production for production. So if they have
some named grouping in the XSD, I have a corresponding pattern in RELAX
NG. (In some cases, like type derivation and susbtitution groups it gets
more complicated.) I think it is better to have that kind of traceability
where the XSD is the canonical source, though it is certainly open for
discussion.

Well, "mixed content" in XSD includes data-only content. Or to put it
another way, in XSD untyped data-only content is done by having mixed
content but disallowing any elements (hence the maxOccurs='0'). So that
schema doesn't suggest that there can be other elements, it forbids it.
(And, I stress again, the XSD is *not* my schema, and out of my control.)
