I think the plan is that we keep this as "required" and I fix the schema 
generation to match this.

The only other use of "required" default is for the "src" attribute of 
mglyph. Here we plan to leave it optional in the schema (for mathml2 
compatibility) and amend the existing note on the deprecated maction 
attributes to say that if the deprecated mglyph attributes  are _not_ 
used then that indicates  MathML3 usage and in that case the src 
attribute should be used.
