If something from primnodes.h (XmlExpr) needs something from
parsenodes.h (TypeName), should I just move the former to the latter,
or is there some major semantic dividing line between the two? Or
maybe TypeName should really be a primnode?

Anything in primnodes should never need a TypeName. Post-parse-analysis
representation of type info is as a pg_type Oid. If you think you need
something else, let's have a discussion about why. (Perhaps you need to
split XmlExpr into two different node types, one for raw grammar output
and one for parse-analysis output?)
