[jdom-interest] Nested namespaces and attribute prefixes - help?

[Philip Nelson]

Sorry, but I can't figure out exactly what you are trying to do or what is
going wrong.  Could you send some java code?  JDOM version?

Yes, your myattr attribute will be in the correct namespace if it is parsed
from a file.  If you are building the document in code, you will have to show
some examples for us.
