Okay, okay... now get it.

So, it's not relative. But localhost is relative. So it's an absolute
address with a "relative" localhost at the root. I'm not trying to argue
semantics, I'm just saying that there is a relative component to this
address. That's not to say that it's a relative URI.

I came across this namespace declaration in a someone else's document (which
I told him to change), but got stuck on the meaning of file:///foo.xsd. I
see now that the third slash means "localhost", which of course I should
have known but I got mentally blocked on file path representations. Now I'm
back aboard the clue train.
