[jdom-interest] namespace declarations in the top element

[John Caron]

I am constructing a JDOM Document, then using XMLOutputter to write an XML
doc. I want to put namespace declarations in the top element, eg:
<catalog name="Example" xmlns=http://www.unidata.ucar.edu/thredds
xmlns:xlink="http://www.w3.org/1999/xlink">

I cant write these attributes directly, so how do I force them to appear
there, instead of multiple times in contained elements that use those
namespaces?

thanks for any help.
