That might be true for you, though there are plenty of people using XSLT
meta-stylesheets to generate XSLT, and it's often quoted as being one of
the (few?) advantages of the XML-based syntax of XSLT that it makes it
easy to generate a stylesheet as the output of a stylesheet. The fact
that XQuery isn't XML does make it quite tricky to generate an XQuery as
the output of another XQuery.
