XQuery 3.0 is nearing completion

XQuery 3.0 was initially called XQuery 1.1, but the Working Groups later decided to align the names of these new versions of XPath and XQuery. The relationship between the two languages is unchanged; XPath 3.0 is largely a subset of XQuery 3.0. The Working Groups decided not to publish a new version of XQuery 1.0 and XPath 2.0 Formal Semantics. The rules for static type inferencing are now implementation-defined. Publication as a Candidate Recommendation means that XQuery 3.0 is largely complete and has been widely reviewed. The Working Groups are gathering implementation experience before requesting that the specification advance further.
