This is a further discusion of the thread "XdmNode toString, Processor.writeXdmValue prb " but it was getting so indented its hard to read. I ran into another related problem in searializing using Processor.writeXmmValue and XdmValue.toString() and also using the xquery run() method. Suppose I have a document with declared namespaces: -------- <t:test xmlns:t="http://xproc.org/ns/testsuite" xmlns:p="http://www.w3.org/ns/xproc" xmlns:c="http://www.w3.org/ns/xproc-step" xmlns:err="http://www.w3.org/ns/xproc-error"> <t:input port="source"> <t:document> <doc>Text</doc> </t:document> </t:input> </t:test> ---------- If I run the xquery '//doc' and serialize with XQueryEvaluator.run() or with Processor.writeXdmValue() I get ------ <doc xmlns:t="http://xproc.org/ns/testsuite" xmlns:p="http://www.w3.org/ns/xproc" xmlns:c="http://www.w3.org/ns/xproc-step" xmlns:err="http://www.w3.org/ns/xproc-error&quot;&gt;Text&lt;/doc> ----- My first question is: Is this the expected output ? Should the unused namespace declarations be output on this node ? Second, if instead I use my own serializer using the ComplexContentOutputter I get ----- <doc>Text</doc> ---- This is what I would nievely assume is correct. Now here's the fun part. If instead I run the xquery <wrap>{//doc}</wrap> Using my serializer I get -------- <wrap> <doc xmlns:t="http://xproc.org/ns/testsuite" xmlns:p="http://www.w3.org/ns/xproc" xmlns:c="http://www.w3.org/ns/xproc-step" xmlns:err="http://www.w3.org/ns/xproc-error&quot;&gt;Text&lt;/doc> </wrap> --------- And when I run document { //doc } I get ------ <doc xmlns:t="http://xproc.org/ns/testsuite" xmlns:p="http://www.w3.org/ns/xproc" xmlns:c="http://www.w3.org/ns/xproc-step" xmlns:err="http://www.w3.org/ns/xproc-error&quot;&gt;Text&lt;/doc> -------- SO what appears to be happening to me is that the ComplexContentOutputter is only removing redundant namespace declarations if they appear on the root node (either an element or a document). My questions are 1) What is the expected behaviour ? Is it expected that unused namespace declarations be output ? 2) Any suggestions on a seraialization strategy which universally removes unused namespace declarations from all child elements ? Is that a reasonable thing to expect possible ? Thanks for any suggestions -David
