No, its' the opposite. This is a key problem with UUIDs as I argued in my later mail

Not every thing that looks like a URI really works like one. For example file:///... URIs 
usually are not global identifiers, and even though software accepts it, it's just a hack 
people use to get around software that forces them into this kind of situation. 

UUIDs are not a good way to go. They make it look like there is agreement, when in fact
conceptually things are just as broken.

Something I'd have to look into.
