Well, so far WSDL 1.2 defines some specific bindings, but does not say that other bindings are excluded. So I would conclude that in principle WSDL 1.2 can bind to 'everything'. The issue, I think, is whether we want to say that those bindings are Web services if no alternative SOAP/HTTP binding is also provided.

I don't fully understand your position here. Following your first statement, I would say that a service described by WSDL and offering two end points, one bound to SOAP/HTTP and another bound to CORBA, would qualify as a Web service.
