The W3C XQuery working group has posted a new candidate recommendation of XQuery Update Facility. XQuery as it currently exists is basically just SELECT in SQL terms. XQuery Update adds INSERT, UPDATE, and DELETE. More specifically it is:

• upd:mergeUpdates
• upd:revalidate
• upd:applyUpdates
• upd:insertBefore
• upd:insertAfter
• upd:insertInto
• upd:insertIntoAsFirst
• upd:insertIntoAsLast
• upd:insertAttributes
• upd:delete
• upd:replaceNode
• upd:replaceValue
• upd:replaceElementContent
• upd:rename
• upd:removeType
• upd:setToUntyped

The following features are considered to be at risk:

• Revalidation modes other than "skip"

• the Update Facility Static Typing Feature

• XQueryX Conformance

They may be removed if implementations of them do not exist at the end of the Candidate Recommendation period.

Comments are due by August 31.
