You might get different answers on a different list.... But I do think it's
true that XSLT continues to have much wider usage than XQuery.

I think the reason for that is primarily that people want to do transformation
(which retains most of the information in a document, but in different form)
rather than query (which extracts small amounts of information from a
document).

Although XQuery is capable of doing transformation, XSLT is better at it for
two reasons:

(a) the built-in rule-based processing model using template rules

(b) the customization capability provided by xsl:import

neither of which have any parallel in XQuery.

XQuery is much better at doing complex joins, but that's not the kind of
processing people are mostly doing.
