Seems like a problem with DOM Level 3 test case documentnormalizedocument11. <assertEquals actual="nodeName" expected='"address"' id="documentnormalizedocument11_namespaceDeclarations" ignoreCase="false"/> should have been <assertEquals actual="nodeName" expected='"acronym"' id="documentnormalizedocument11_namespaceDeclarations" ignoreCase="false"/>
Can confirm Neil's findings, was about to report this myself! However, I can't quite work out what the test is supposed to be doing in any case. It only seems to be checking element nodeNames, which should be completely unaffected by the normalizeDocument call in any case. I would have expected it to check (a) that the namespace declaration Attrs were gone and (b) that the nodes were still in the same namespaces.
