All other properties of the copied nodes are preserved. The copied node may be a document node. This means that the document-uri property will be copied. However, in section 2.1.2 Dynamic Context of XQuery 1.0 it is stated that "This means that given a document node $N, the result of fn:doc(fn:document-uri($N)) is $N will always be True, unless fn:document-uri($N) is an empty sequence." The query copy $N := doc('data.xml') modify () return fn:doc(document-uri($N)) is $N demonstrates that this is violated. I would expect that the document-uri property should not be copied, and that document-uri($N) should be the empty sequence. 81403 1 john.snelson 2013-01-15 16:54:36 +0000 The XQuery WG discussed this on 2013/01/15 and agreed that the suggested change should be made in the XQuery Update 3.0 working draft. Implementations of XQuery Update 1.0 can consider making the same change. 113081 2 tim 2014-10-14 09:34:58 +0000 I'm reopening, as I'm unable to find the agreed change in the XQuery Update 3.0 editor's draft. 113083 3 john.snelson 2014-10-14 09:36:48 +0000 I'm closing this bug again, as the decision is recorded in changes.txt and will be made in the course of time.
