But, a "" namespace is illegal per w3c DOM.
I have created XML with other tools and they do not do this. When you
assign xmlns="http://www.someplace.com" all it's children are part of that
namespace unless you explicitly say other wise. So when I set the root
element to xmlns="http://www.someplace.com" all it children are in that
namespace, so for JDOM to add to the first level children an illegal
namespace of "" this file is now invalid when I try to convert a JDOM
document to a w3c DOM Document an exception is thrown stating that "" is
illegal for a namespace.
I should NOT have to assign a namespace to every element. I am creating XML
files that must be validated against a Schema and the schema works as I
stated, that all children are in the same namespace as the parent unless

You *must* assign the namespace to each element you create. A child element
does not automagically get the parents namespace which means it is in the ""
namespace. This is by design and was *HEAVILY* discussed here.
