[jdom-interest] exception with xml:lang

[Clark, Stacie]

On July 3,  Gabor Grief wrote that he was still getting an exception thrown
when using the xml:space namespace. I looked further in the archive but
could find no resolution (of course I didn't read the entire archive, either
:-)  I am getting a related exception with xml:lang using a checkout from
today and the xerces parser.

The xerces parser is able to parse the document with no problem.

If I remove the offending lines, which look something like:
<label href="xpointer(//item[@type='gpsi:computation.netIncome'])"
xml:lang="en">Net income</label>

Then jdom can parse the document.
