The reference SW  *IS* the standard (part 5 of MPEG-4 actually) and
as such it is standards-compliant by definition.

There are some very minor discrepancies between the text (in the case
of Visual, part 2) and the reference SW (part 5). 
These are being corrected as we write.
Sometimes this requires an update in the text, sometimes in the SW.
To the best of my knowledge, there is no reason to assume that the 
Microsoft version of the reference SW is more affected by these pesky
little details than the MoMuSys part of it.
Best,
Rob
