Ah. Here's you've made an important clarification, Simon. Expressed this
way, I agre with you that the W3C's use of URI has sown confusion. Hpwever, I
sympathize with the various WGs involved: it is a tremendously hard set of
problems that they have taken up URIs to solve, and I don't think any body
could get such things uniformly right.
This is why I argue for *less* specification and oversight over the use of
URIs, not more.
For instance, I think the proscription against relative URIs in namespaces was
a bad idea. Not because using relative URIs are a good idea (I'm not getting
sucked into that one), but because it was adding a puzzling level of
stringency to a namespace spec that had already tried to stay at arms length
from URIs. I would argue, as John Cowan posted, that namespaces should be
stated as a string with the syntax of URI reference. This would reduce the
regulation further (and have the effect of nullifying the "namespaces must be

I would argue that since signifiers in re already bring an infinite potential
for confusion, that adding another infinite potential has no discernable
