Part of the aim of the integration with XML Schema in XSLT 2.0 is being
able to detect Xpath expressions and other constructs that are
inconsistent with the schema for the data. The idea is to enable static
checking through the type system that any path expression is capable of
producing results. It's a bit of an open question how far systems will
be able to do this in practice; I think the more draconian end of the
spectrum is likely to lead to too many errors reported against
constructs that are actually perfectly reasonable. But I think there's
quite a lot of potential for XSLT 2.0 processors to offer improved
diagnostics in this area, e.g. by providing users with control over the
level of warnings that are output.

Yes, that is similar to what I need, but the tools that
Holman provides
work on his "literate" stylesheets, not on regular stylesheets.
I guess I could write an XSL transformation that covers the
main cases
(XPath in <xsl:template> <xsl:* select>, etc). But trying to
cover all the
cases (variables, XPath expressions embedded in output element using
{expr} syntax, etc.) may be too much. And still, without
"executing" the
original stylesheet it's even more difficult, if not impossible, to
combine paths, for example in nested templates.
Anyway, thanks for the document.

Even something that would generate the list of XPaths
referenced by
an XSL stylesheet will suffice (then it would be quite
easy to parse
an XML file, generate paths for each node and match them with the
paths in a
stylesheet).
Does anybody know if such a tool for XSL exists ? Or has any
suggestion of how to write it or knows of any XSLT
processor with an
API that would
allow
me to do that ?
G. Ken Holman described a similar tool in his presentation
"Synthesizing stylesheets using "Literate XSLT"" at this year's
Extreme Markup conference:
