Well actually, particular since one can now 'resolve' a "urn" there is no
difference between a URI and URL under any circumstance i.e. the URI
completely supercedes and incorporates URL and URN. Then again, I just read
the tea leaves... and at least when I write a "riddle" I label it as such

From the rec:  "The attribute's value, a URI reference, is the namespace
name identifying the namespace. The namespace name, to serve its intended
purpose, should have the characteristics of uniqueness and persistence. It
is not a goal that it be directly usable for retrieval of a schema (if any
exists). ..."

My understanding is that this sort of wiggly language is there on purpose as
a compromise between those that desired vs. those that did not desire the
requirement to resolve a namespace URI. The REC clearly does not require
resolution, however it does not prohibit resolution.

I don't think any can of worms would be opened because people _do_ expect
that "http" URIs are resolvable. Again the principle of least surprise.
Certainly people that _choose_ to use "http" URIs ought expect resolution,
its not like there is a shortage of "urns" or something. I would clear
things up. I think that standardizing common practice is usually a good
