Hi Martin,

Right.  Like COM and IUnknown/QueryInterface.

Heh. 8-)  But since IUnknown (or equivalent - I don't remember the
CORBA equivalent) can only be used to discover the specific interface,
and not *use* the service, eventually, component-specific semantics are
required to be understood.  Does that help?

So, despite CORBA and COM having some generic methods, the larger
picture of a CORBA/COM connector is that semantics are specific to the
component.

Thanks for the feedback.  When we write this up, we should be as
specific as possible, and this should be reflected.  We could talk about
how WSDL-over-GET, or WSIL, or other uses of GET with Web services, are
used in a similar way to IUnknown/QueryInterface.
