What you claim to identify as a distinct property of XQuery is common to
XSLT. Both XQuery and XSLT are declarative, not procedural. Neither enforce
any particular implementation strategy. As far as XQuery being more
"succinct" than XSLT, that's due to XSLT's XML syntax, not due to its
declarativity.
