Re: [sca-bindings] Issue 25: Does binding.ws imply SOAP

[Mike Edwards <mike_edwards@uk.ibm.com>]

Eric,

I agree, that <binding.ws/> MUST
support SOAP, or must support SOAP over HTTP is a reasonable position -
and can help interop.
(We might go further and demand that
WS-I Basic Profile must be supported for the "unadorned" <binding.ws/>)

With regard to the "alwaysProvides="SOAP"
intent, there we need a discussion.

If THAT were required, then it would
imply that <binding.ws/> ALWAYS means "SOAP" message format
- and that no other format
is allowed.   This is a further
step.  Requiring that the binding implementation support SOAP is not
the same as requiring it to support
SOAP at all times.  This requirement
could render valid WSDLs invalid, for example if they used a "RESTful"
style XML format for the
exchanged messages, rather than SOAP.

Do we want to go this far?

Following all of Mike's points....

Folks, 

I agree with the general direction advocated here:

1) <binding.ws/> implies a WSDL-related binding

2) <binding.ws/> SHOULD imply a SOAP binding

3) <binding.ws/> WITHOUT an explicitly supplied WSDL MUST support
SOAP & HTTP 
I believe we require supporting binding.ws with nothing
additional supported, as in:
"<binding.ws/>"

Coupled with Mike's statement above, this implies that a conforming implementation
MUST support SOAP, even if SOAP is not used in a particular configuration.

Is that the question or is the question more specifically that it is always
true that a binding.ws implementation "alwaysProvides" "soap"?

If you can't tell, I'm slightly lost as to the actual issue.
