Cool!

There is only one little thing. Right now the spec allows "aliases" for
symbol space names. Those aliases are not required to be IRIs (otherwise I
do not see a purpose for them). So, something like

"abc"^^foobar&>%$

is also possible (in principle). It would be wrong to write it as 

"abc"^^<foobar&>%$>

since foobar&>%$ is not an iri.

On the other hand, I do not see those aliases as terribly useful in any
form or shape. I included them because Jos wanted them. So, I would be
perfectly happy to throw them out.
