Ugo,

May be so. If it is defined in AC009, I am interested in knowing how AC009
helps in explicit definition of service behavior + the requirement below.

Cheers,

Suresh,
Isn't semantics already addressed by AC009?

Hi all,

While discussing reliability of web services in RTF, we hit upon the issue
of how to define the "behavior"
of a web service. Service Defn. based on WSDL only allows the interface
description, and is silent
about what the service will do (semantics). For example, a service
description that takes two parameters and does an "add"
may do a multiplication. The question is whether WSA should "enable" such
semantic definition of the behavior
of services. There may be multiple means to accomplish this, including
"design by contract"[2]. Many may argue that
such a definition may not be complete in most circumstances. In any case,
what do you think?


Here is the item tabled for debate from [1] 
D-AR019.2.2 The functional behavior of two or more web service implementing
the same version (see AR019.3.1) of a web service definition is identical.
	[<sd> the reverse may be true also - two implementations may have
the same behavior but different definitions, but is not worth mentioning
</sd>]

Thanks,

-Suresh
