The program manager for the MSXML group says that they are "just considering
it," and there's a lot to consider. For example, how would they support
aspects of XSLT that require the whole document to be in memory, such as the
"following" axis? Or would they just not support it? 

XSLT's approach of converting a tree to a tree as opposed to just being a
filter that you can pipe data through does buy you something, and I imagine
they'd have to give up some of that when using a stream-based approach.

Another example of something that would really be complicated by a
stream-based approach. 

Of course, I haven't written an XSLT processor, so maybe someone who has
could provide some perspective?
