[cxml-devel] Bugs in handling namespaces

Hi David,

I've attached a document that I then manipulate, to demonstrate the
problem I'm still having... I insert a new child <use/> in the document,
then add an "xlink:href" attribute. This somehow mangles the xlink
namespace declaration in the <svg/> element. BTW, note that the
graph.xml here is the same as the one I had sent with the clone-node
problem. I have made sure when parsing that the DTD is available and
included when the document is parsed. I don't know if that will make a
difference in your testing.

Sunil
