Hi, Default namespaces and empty prefixes have been a sore spot for a long time - Xerces/Axis 1/Axis2 have not provided consistent behavior in this area, and we've covered the issues in this troubleshooting entry:
http://ws.apache.org/muse/docs/2.2.0/manual/troubleshooting/default-namespaces-xerces.html The problem with your sample is that it mixes the concepts of default namespaces with empty prefixes. When an element has a default namepace (xmlns="..."), there is no prefix, so the QName is just the local name and URI; when it has an empty prefix (xmlns:="..."), the element has a complete QName. We've chosen to avoid default namespace support because the two things are so often confused and lead to interop problems between stacks.
