Fixed in CVS (tree.c 1.339). After applying the patch on libxml2-2.6.17 the output is: '<?xml version="1.0"?>\n<a xmlns="http://a/";><b xmlns="http://b/"/></a>\n' Ns of <b/>: 'http://b/' '<?xml version="1.0"?>\n<a xmlns="http://a/";><default:b xmlns="http://b/"; xmlns:default="http://a/"/></a>\n' Ns of <b/>: 'http://a/' That is a correct XML, but still does not satisfy me. A prefix has been added to <b/> and the unneccessary namespace declaration is still there. For my needs that is still unacceptable. I implement an XMPP implementation and for backward-compatibility with many Jabber clients I need to use default namespaces (no prefixes) in some places. I think a function to remove (or override) namespace declaration from a node is what I need and I will request it via Bugzilla.
