Should be, but the REC language is broken here -- I'm pretty sure the
intent was for this constraint to apply to two _distinct_ element
declarations, which means at least one of them would have to be local,
as all refs to a named top-level element decl produce the _same_
element decl.

I'm not aware of any processors which complain about this case.
