1) Domains are costly. Some communities may not want to
	have to afford them.

2) As Koen has pointed out in a previous mail, some tags can
	also have values. And as Koen says, it's there that
	things such as internationalization can come in very
	handy.


This is really the point where people that try to reduce syntax
complexity by introducing limitations can learn something.
What happened e.g. with URLs is that they were not intended
(at least by some) as something people would use. But they
got used because they were usable. That then lead to the
demand for internationalization. It's very difficult to
claim that something will not go that way unless you are
really strict and go back to something such as numbers only.
