Why is it critical that a web service have only one interface?  I don't know
of any mechanism by which there could be more than one, but what would be
the problem with that if someone figured out how to do it?

Chris, I just noticed something else;

> "A web service is a software application or component identified by a 
> URI, whose interfaces and binding are capable of being described by 
> standard XML vocabularies and that supports direct interactions with 
> other software applications or components through the exchange of

Other than the concerns I've already raised about "binding", "direct
interaction", and the necessity for a distinction between component and
application, I just noticed that "interfaces" is plural.  Is there any
particular reason for that?  I believe it's critical that a Web service have
a single interface.  Perhaps it's just a terminology issue, but I'd
appreciate clarification.

Thanks.
