> From my examinations, it would appear that XQuery is a superset of XSLT.
Don't you have that backwards?
Xquery is essentially XSLT 1 (ie no xsl:for-each-group or
xsl:analyse-function) plus function definitions (in XSLT 2, but available
in several xslt 1 systems as an extension) and plus Xpath2 (also in XSLT2
unfortuately) and without xsl:apply-templates and with some dodgy ad hoc
syntax that looks a bit like xml but isn't.
Not having apply-templates makes it allegedly easier to convert into
optimised database queries but makes it very hard to do most of the
transformation jobs that xslt does. It certainly means that Xquery is a
much simpler language than XSLT.
I'd hate to have to write the docbook stylesheets (or the xmlspec
stylesheets used to generate the Xquery spec) in Xquery rather than
XSLT.
