No.
A.rng
<define name="foo" combine="choice"/>
After parsing the above definition, combineMethod="choice" and ref is
defined, but haveHead is false.
Then if we see the next definition,
<define name="foo"/>
combineMethod is still "choice" and ref is defined, and this time
haveHead is changed to true.
So I think we need three fields.
