Just decide what you want and implement it. Namespaces are not standardized
yet, and are still the focus of some debate. Some. like me, believe that
they are syntactic sugar for things you can already do in XML with
attributes. The issue of what the URL points to is currently entirely open.
The only guarantee is that the absolute URL, plus the part of the element
name _after the colon_ is uniquely associated (by unspecified means) with
some definition of semantics. The putative purpose of namespaces is to
provide applications that might need them with globally unique IDs for
element types.
They are an additional layer on top of XML and don't affect XML syntax.
They are also experimental, and not standard at the moment.
