I don't know how many times I should reply to the same assertion that we
aren't trying to close this gap.
Our XPath 2.0 task force is working together to define both syntax and
semantics for the path expression language. XQuery will also have some
syntax that is not in XSLT, and XSLT will have a lot of syntax that is not
in XQuery (the XML-based syntax).
These are my opinions right now. They may be quite different from the
opinions of Software AG, the W3C XML Query Working Group, or the opinions
that I will have after reading and considering your response.
