+1 -- including the part about making having an
explicit service/callback/binding/@uri
value illegal.

ISSUE 19: Web Service binding should allow #wsdl.binding with reference
targets
Simon,
I'm not sure I follow your proposal where it deals with
Callback URIs.
For a service with
a callback, I would not typically expect any URI to be present on the service
relating to the
callback, since the
callback address is applied dynamically at runtime. So a blank URI must
be allowed
(if a URI is supplied it
implies that the callback goes somewhere else other than the client - I'd be
happy
to make this capability
illegal).
I can see the
possibility of needing to express an endpoint address for the callback on the
reference - since
a URI needs to be
created for what is effectively an endpoint.
However, unless I've got confused - this is not what
the text below is saying.
Yours, Mike.

RE: [sca-bindings] ISSUE 19: Web
Service binding should allow #wsdl.binding with reference
targets
This is the completion of my action to post an
updated proposal for the resolution of this issue.
I'd like to focus on the words in
lines 82 and 83 and consider the 4 cases of references, services, reference
callbacks and service callbacks.
REFERENCES
In our resolution of BINDINGS-17, we agreed that
references with bindings must be "bound". For this binding.ws case of
wsdlElement="...#wsdl.binding...", the reference becomes bound by
specifying a URI attribute on the binding. So the existing specification
text in lines 82 and 83 is correct and needs no change.
SERVICES
The endpoint address URI can be
provided by a URI attribute on the binding, or it can be provided via the
implict URI as defined by the Assembly specification (see points 2 and 3 in
section 2.1, lines 105 to 107). So the existing specification text in
lines 82 and 83 is incomplete because it does not allow for the second of
these possibilities.
CALLBACKS ON REFERENCES
For callbacks, the service and reference roles are
reversed and I believe the rules in section 2.1 should apply to binding
elements specified in the callback element of a reference.
CALLBACKS ON SERVICES
For callbacks, the service
and reference roles are reversed and I believe the resolution to BINDINGS-17
implies that binding elements specified in the callback element of a service
must be "bound".
PROPOSAL
The following proposed wording change embodies the above
points:
In the
Web Service binding spec, lines 82 and 83, replace "...the endpoint address
URI for the SCA service or reference must be provided via the URI attribute on
the binding" by "...the endpoint address URI for an SCA reference or the
callback element of an SCA service MUST be provided as the URI attribute on
the binding, and the endpoint address URI for an SCA service or the callback
element of an SCA reference MUST be provided as specified in section
2.1".

We noted a
couple things about the new text (starting at “or by ...”).
1) These are primarily relevant when the
binding.ws is on a reference, not a service or callback.
2) If it uses SCA targeting mechanisms, the
targeted service must provide a binding.ws that refers to the same WSDL
<binding>.
By “same” I mean a <binding> element with the same name in a
WSDL document with the same targetNamespace as the URI used in the
@wsdlElement attribute.
Reminder we are talking about this case:
<reference
name=”foo”>
<binding.ws
wsdlElement=”http://some.domain/some/ws#binding(bindingName)“/>
</reference>

On last week's sca-bindings call, I took an action to post an
updated proposal for the resolution of this issue, based on some words posted
by Michael Rowley in the chat room. Here's my proposal.
In
the Web Service binding spec, lines 53 and 54, replace "...the endpoint
address URI for the SCA service or reference must be provided via the URI
attribute on the binding" by "the endpoint address URI for an SCA service MUST
be provided as the URI attribute on the binding, and the endpoint address URI
for an SCA reference MUST be provided either as the URI attribute on the
binding or by the endpoint address implied by a reference target URI or wire
target URI".
