Not to make the binding framework more complicated than it has to be or
less useful to "nosy" SOAP apps, I think that an ioctl-analogous
would make the framework more complete, let alone addressing the need
for protocol selection that Marwah was alluding to.  The semantics may
be built around some simple get/set, e.g. fetching error codes/messages
from the transport when a soap request has failed, or switching from
TCP to HTTP (to slip through firewalls).  In more far-fetching cases,
which MUST only be optional for framework implementations, app modules
may be pushed downward, well beneath SOAP.
