A family of Microsoft word processing software products for creating web, email, and print documents.
If you have an MSDN subscription with some unused support incidents, it may be worth blowing one of them asking this question. But I'd verify that those incidents can be used for Mac Office issues first. My suspicion is that no-one outside the Mac Office dev. Team could answer this question reliably, so it's really a question of trying to make a connection with them ( which is not likely to happen in here). It may even be worth firing off a feedback message with your contact details via Word help-> feedback, even though it is a one-way system. As a general observation, the amount of detailed technical information of this kind seems to be much lower than on the Windows side, but why I cannot tell you - probably money/ resources, but maybe not.
