Yes, but this is an intrusive method: you need to modify the syntax of
the instance documents and I don't think the MathML working group will
modify the syntax of MathML which is a recommendation to fit into the
W3C XML Schema mold ;=) ...
The XML Schema WG itself hasn't used it, otherwise they could have used
different complex types for local element definitions and elements
references for instance!
I see this more as a workaround for custom vocabularies than something
used by mainstream specifications...
