RE: [XSLT2.0] XML Schema WG Comment 1/2 [datatypes namespace]

Thanks for this comment.

Speaking personally, I'm glad you pointed this out. I was aware of the
problems with the datatypes namespace but I had forgotten that we still
had a reference to it, and I would love to see it quietly disappear.
