There's a specification called "XQuery 1.0 and XPath 2.0 Formal
Semantics" [1], which details the semantics of XQuery 1.0 with a more
rigorous mathematical notation - this document may possibly be
discontinued as the XQuery Working Group publishes the XQuery 1.1 range
of specifications.

Not at all - there's lots going on for XQuery 1.1.

You can read the XQuery 1.1 requirements document [2] to find out what
the working group has been adding to XQuery. Some highlights (for me)
include:
1) Higher order functions
2) Grouping and windowing
3) Try/catch
