The W3C XQuery working group has posted the candidate recommendations of XQuery Update Facility, XQuery Update Facility Use Cases, and XQuery Update Facility 1.0 Requirements. XQuery as it currently exists is basically just SELECT in SQL terms. XQuery Update adds INSERT, UPDATE, and DELETE. More specifically it is:
upd:mergeUpdatesupd:revalidateupd:applyUpdatesupd:insertBeforeupd:insertAfterupd:insertIntoupd:insertIntoAsFirstupd:insertIntoAsLastupd:insertAttributesupd:deleteupd:replaceNodeupd:replaceValueupd:replaceElementContentupd:renameupd:removeTypeupd:setToUntypedThis is one of the last two pieces before XQuery 1.0 is really complete. (The other is full-text search.)
