CR 20: amalgamated proposal

To: "public-ws-addressing@w3.org " <public-ws-addressing@w3.org>

Here is a joint proposal to resolve issue 20.

The proposal does the following:

a) Gets rid of defaulting in the Core, but allow bindings to specify 
defaults.
b) Does not change the cardinality of [destination] or wsa:To in the Core
c) specifies that messages on the "back channel" must have the value of 
'anon' for the [destination] property.
d) specifies 'anon' as the default for messages on the back channel.
e) incorporates wordings similar to Paul Downey's which say that outside 
of this particular scope this spec does not define any particular 
semantics for the 'anon' URI.

Please note that this proposal keeps the resolution text of CR4, which 
either got removed as a result of resolution of CR15 or was an editorial 
oversight (I have already sent a separate email for this). If we do not 
keep the resolution of CR4 then the editors will have to change the 
wordings to make it fit better.

Proposal:
--------

1) In the Core spec [1], section 3.2, change:
-----
   /wsa:To
      This OPTIONAL element (whose content is of type xs:anyURI) provides
the value for the [destination] property. If this element is NOT present
then the value of the [destination] property is
"http://www.w3.org/2005/08/addressing/anonymous".
-----

to:
-----
   /wsa:To
      This OPTIONAL element (whose content is of type xs:anyURI) provides
the value for the [destination] property. A binding of Addressing to a
specific protocol may define a default value for wsa:To. In the absence
of such a default, a value for wsa:To MUST be specified.
-----

2) In the SOAP binding spec [2], in section 5.1 add:
-----
{The para below is the resolution text for CR4 and included here for flow}
When "http://www.w3.org/@@@@/@@/addressing/anonymous" is specified as
the address of an EPR, such as the ReplyTo or FaultTo EPR, the
underlying SOAP protocol binding provides a channel to the specified
endpoint. Any underlying protocol binding supporting the SOAP
request-response message exchange pattern provides such a channel for
response messages. For instance, the SOAP 1.2 HTTP binding [SOAP 1.2
Part 2: Adjuncts] puts the reply message in the HTTP response.

{The next 2 paras below are new}
Messages on such a channel must have a [destination] property value of
"http://www.w3.org/@@@@/@@/addressing/anonymous". Additionally, this is
the default value of such responses if the [destination] value is not
specified.

Outside of this usage, this specification assigns no particular
semantics to the use of "http://www.w3.org/@@@@/@@/addressing/anonymous"
for the [destination] property in this binding.
