[jdom-interest] xmlns="" in children elements of root

[Rodney S. Foley]

Thanks Alex.

The QUESTION from the FAQ:

"Why do I need to pass in a Namespace to getChild(), when the child element
I'm looking for has no namespace declaration?"

It states that children inherit their namespace from their parent.

It states that when reading you programmatically there for have to get the
children with the namespace. 

It states that when creating you programmatically do NOT have to provide the
children with their namespace when .

But then it contradicts itself and states that if you leave out the
namespace programmatically when creating that you will end up with a ""
namespace. 

And if I add the namespace to every element then it creates correctly,
however this seems like extra work that should not need to be there. That if
I add a child to an element, and it does not have a "xmlns" declared that it
gains the parents namespace.

This seems cleaner from a user of the API's point of view.  And keeps it
more inline with how the XML namespace spec READS on w3c, and therefore less
confusing.

There's a FAQ entry on jdom.org about namespaces that talks about this.
