Comment 9 for bug 114441

rickg,
   Would you mind leaving this open and marked M20 instead of marking it
RESOLVED, so it is easier to find doing bugzilla queries? Or you could
assign it to <email address hidden>? (It went to you by default since the
component is HTML Element.)

Added "helpwanted" in case we can find an eager mozilla-ite to look into this.
As erik points out, we may be able to leverage from the great MathML work.

BTW, IE5 has this feature and does "advertises" it as one if its I18N features.
