Did you have a proposal? One easy thing to do in the next version of MathML
(who knows when that would be) would be to extend the legal values to
'doubleline" or "solidsolid" or some such.

In general, this is a losing game because someone may next want dashed
double lines or dashed lines with arrows on each dash or...  Without the
programability of TeX, a finite list of the higher use cases is all that
can be done for MathML (and HTML-based languages in general).

My bigger concern is that adding features raises the bar for implementers
that are already having trouble implementing features. Having characters
that stretch for spanning rows/cols in an mtable seems much more important
and that is unfortunately not widely implemented.
