I'm afraid I don't understand this question. Could you please clarify?

The MathML CD is simply to ensure that
these two emerging standards share MathML's (fixed) ontology.
OpenMath uses CDs to extend its ontology, however I'm not aware
of plans for any CD specifically for a single computer algebra system.
In fact, it would be pointless to do that in general. The idea is to
write a CD addressing an *area of mathematics* and then write a *phrasebook*
to translate from OpenMath into the specific representation of the computer
