I guess MS does perform the same level of validation if the version is not
equal to 1.0.

Problem is that I cannot seem to succeed in executing the standalone XSLT
test suite :(

I'll see if I can find time to look into the broken changes. With broken I
mean broken compared to the MSFT implementation. 

Is that ok for you ? If not, it might be best to revert all validation

Ok. Point taken.

I agree with you. We should not implement MS bugs, but we should stick to
their implementation as close as possible (as this will allow tests to pass
on both implementations, therefore allowing us to catch regressions/changes
in both implementations).
