Also I think we may focus the discussion on the semantics (the meaning) of
services and functions first rather than the meaning of vacabulary used in
the description document, even the semantics/meaning of "city" is different
in different parts of the world. So when we use "city" in WSDL or any other
document, do we need to clarify that the definition of "city" means that it
should have more than 5000 people or 25000 people, in UK or in USA or
somewhere else. CS people may not be capable to deal with such cultural

Xuan Shi -
   Let me once again point you to the slides from my XML talk [1] - I 
contrasted Xlink (which is essentially identical to what you propose 
to do for services) to RDF, showing why they are crucially different. 
There's a big difference between what you have below (because I am 
unsure what "roomtype" is and what values are allowed) and 
http://ex.org/hotel#roomtype which could dereference to an RDFS or 
OWL document which would exactly answer that question.  I could also 
then tell if Holiday Inn's "roomtype" and one at some Inn in Japan or 
China was the same thing, or something that might be different -- 
these are not minor differences - the focus on links is crucial to 
understanding the Semantic Web as I said in that talk
