SWBPD WG is working on this problem, see

http://www.w3.org/2001/sw/BestPractices/XSCH/xsch-sw-20041216/

particularly section 2.
It provides ability to use user defined XML Schema datatypes directly in 
RDF and OWL, but does not provide the mapping of facets to triples that 
your example shows.

I hope a version for public review will be available sometime fairly 
soon (but not real soon!)
