Absolutely. However:

Nope, it is definitely not correct. See [1], the URI you mention is to
be used by XML Schema itself to refer to it's build in datatypes. 
The XML Schema spec explicitly gives a URI for an XML application other
than itself to use it's build in datatypes, that URI is

http://www.w3.org/2001/XMLSchema-datatypes

So, to use the Int type in a language other than XSD one must use
something like the following:

http://www.w3.org/2001/XMLSchema-datatypes#int

I believe the prefix is an irrelevant subject, as long as known prefixes
are not used; using a widely used prefix (although perfectly legal) may
cause confusion.
One thing that worries me is the notation of facets; I don't know how
common this is but I guess it should be accepted by a WG since it's
inside a recommendation.

Finally, there is the subject of Type Libraries [2], that are far more
interesting.
