RE: sparse matrix support in MathML

Michael,

I'm not knowledgeable about sparse matrix representations.  Are there a
couple "standard" ones that are widely supported, and if so, what are
they like?  If not, what is your view to the "pure OpenMath" approach
using csymbol that David Carlisle and Bill Naylor are talking about.
