Finally we get somewhere!

Yes and if the assertions are rdf you use the mailto: URI for that.

Quite, which is why it is entirely wrong to use the namespace name
as the URI for rdf assertions about the namespace (and why John C
proposed an alternative URI for that use.)

Unless you are going to rewrite the entire namespace spec

<x xmlns="mailto:timbl@w3.org"/>

is a conforming document and the namespace URI of the document element
_is_ mailto:timbl@w3.org. If you want to make rdf assertions about
the namespace you need to find a URI that identifies the namespace.
The namespace name is not that.
