That's not true at all. If I open http://rddl.org or follow a link to
http://rddl.org in my browser, the URL bar displays
"http://www.openhealth.org/RDDL/"; and I have absolutely no way to know
which namespace is documented.
I think that, on the contrary, this is the major flaw in the current RDDL.

But this would break the simplicity of RDDL and to do more complex
things, I would much prefer using RDF...
My proposal is more than a dirty hack when you think about it. The
document (in whatever location if is) is a container which documents a
target namespace by defining a bunch of resources. This translates
pretty well into RDF to associate resources defined into different RDDL
documents describing the same namespace if you had to.
And it makes RDDL documents movable which IMO is fundamental as well: I
feel very uncomfortable with documents which meaning changes when you
move them!
