[jdom-interest] possible bug with nested namespaces

[philip.nelson at omniresources.com]

Yep, that is a problem.  I'll see if I can find a few spare moments to
reproduce it.  Could you do me a favor and rerun it changing the xlink
prefix to something else?  I seem to remember some special casing for xlink
(but could be wrong on that).
