Service invocation metadata

[Tony Linde]

How do we specify in the metadata for a *service*, the way that that service
should be invoked?

The current schema has minimal Capability and Interface, neither of which
describes how to call the service. 

We need to specify: 

1. what type of service it is (enumerated list: WebService, CGI - any
others?).

2. what parameters it takes and the data types of those parameters (I guess
for a web service we just need to include some part of the WSDL) and how
they are referenced ('name' part of the ?name=value&name2=value2 for cgi).

3. the address of the service (url mostly).

4. anything else?

Cheers,
Tony.
