It's a question of balancing risk, standards conformance, etc.

Using an HTTP URL is wrong, unintuitive and will have bad practical
effects, even if it is safe from a uniqueness perspective.

If we, today, establish the x-mldev namespace then the chances of anyone
accidently intruding on it are incredibly small. So SAX would use:


(if you have registered the SAX domain)

Besides, if we submit an internet draft for an hname: namespace then
nobody is going to go off and invent a clashing one by accident. It's a
question of us taking a little bit of extra effort to do the right thing.
