[jdom-interest] XmlOutputter - printNamespace - NO_NAMESPACE outputs xmlns="", bug?

[Rolf Lear]

Here is a suggestion... Solve lots of problems.

Remove public Element(String tag) constructor..... (also throw an exception
if Namespace in Element(String,Namespace) constructor is null instead of
reverting it to Namespace.NO_NAMESPACE).


;-)

Solve so many problems. Force people to be aware of how namespaces work, and
to choose the namespace at construction time.

In the ways of intuitiveness, this is THE MOST intuitive mechanism, nothing
is "hidden" from the programmer.

When people say "where has it gone?" we just say, "Well, every element in
XML has a namespace, you have to tell us which one to use! ;-)"

Yes it does, it gets the null namespace, and loses the 'current' namespace.
Let's not be religious about this. I think this could be improved by
creating (in JDOM) a default PARENT namespace, so that when creating a new
Element with no namespace, it would get -if any- the namespace on top of the
namespace stack, instead of NONAMESPACE. Since this has backward
compatibility issues, it would require to set a pref somewhere in the JDOM
initialization process.

Don't you think it's an idea ?
