It is not the responsibility ofto resolve the many technical comments that have been presented on OOXML within the JTC1 ballot promise. They cannot promise to fix them.
It is the responsibility of ECMA to handle this, since ECMA formally submitted the specification for Fast Track approval. ECMA is a member organization and, presumably, no one member can speak for that organization.
Moreover, OOXML came out of a particular ECMA technical committee (note I didn’t say “created by”). Anyway, Microsoft can not speak unilaterally for that committee in terms of what changes will definitely be made.
Unless, of course, Microsoft = OOXML as far as ECMA is concerned. If this is the case, I would like to hear this from ECMA because it would simplify matters.
If it is not the case, then promises made may not be promises kept.
