My initial fear in the (b1)-(b2) scale was implicitly defining a bastardized
subset of Presentation MathML, but some of the things that David & Robert
have pointed out give hope that enough can be done with XSLT and/or Javascript
to complete the coverage.

Even so, that doesn't hold much appeal if each author has to send some 
cleverly contrived stylesheets & scripts to each unique browser; that
seems negative progress!

It _is_ appealing if an UA implementer would feel compelled to add a few 
features to thier CSS implementation and supply thier _own_ meta-stylesheet 
that fills in the gaps for thier particular browser.  Then, authors simply
serve normal MathML and everything happens like it should.

[I wonder if Ian is listenning in, and what he thinks of the idea?]

This could still be an issue depending on whether `cut and paste' would get
you the original MathML or the digested MathML.
