I think that in common usage, the term "programming language" means a
language that is computationally complete (Turing-complete). On that
definition, XSLT and XQuery are certainly programming languages, while XSD
and XHTML are not.

(The notion of a "sequence of instructions processible by machines" isn't
needed to make this distinction.)
