I got this message recently that may be of interest to members of this
group. To follwo up, please contact Robert as needed.

>Since then, however, a several groups have looked at using MathML in

>1) Involving enough people from right-to-left language communities,

>2) Assuming 1 can be done, compiling an authoritative statement of
