Thank you for your message.

The intended usage is as shown in


with the id on the ci child of bvar

Which matches the text and the schema.


You are correct to report though that the syntax table for bvar lists

Strict Content MathML is intended to be an encoding of OpenMath, and the
OpenMath Schema allows id on the corresponding OMBVAR element.

Also the MathML2 DTD allowed id on bvar.

So I think the status is that the normative table is to be assumed
correct and that CommonAtt are allowed.

Almost all of the schema is mechanically constructed from the tables in
the spec, but bvar, as the interaction with strict Content MathML is a
bit tricky, was done by hand....

This is a personal response but I'll fix the schema to add CommanAtt
unless working group shouts.
