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.

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>

#wsdl.binding with reference targets
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".
