Re: i049: Predefined default/anonymous action URIs

Marc,
  It says one of the predefined actions "MAY" be used in the absence
of WSDL - just wondering, what ever happened to the Action matching
the first child element of the Body as a common practice?  People are
still free to do so because of the "MAY" but I'm wondering if it makes
more sense to encourage it instead of using ...../message - which really
has no useful purpose/meaning.

I took an action to propose a dual default action URI resolution to
issue 49. This is a simple delta to Jonathan's proposal for a default
fault action URI[1].

Proposal: Update the [action] description in Section 3 of the Core spec
as follows:

[action] : URI (mandatory)

   An identifier that uniquely (and opaquely) identifies the semantics
   implied by this message.

   It is RECOMMENDED that the value of the [action] property is a URI
   identifying an input, output, or fault message within a WSDL port
   type or interface.  An action may be explicitly or implicitly
   associated with the corresponding WSDL definition.  Web Services
   Addressing 1.0 - WSDL Binding[WS-Addressing-WSDL] describes the
   mechanisms of association.  In some systems there may not be a
   WSDL description of a message or fault, in which case the
   predefined action URIs (as shown in Table 3-1) MAY be used.

   Table 3-1. Predefined [action] values
   URI                             Description
   ----------------------          ---------------------------
   http://www.w3.org/@@@@/@@/      For use with generic messages.
      addressing/message
   http://www.w3.org/@@@@/@@/      For use with generic fault
      addressing/fault             messages.

   Finally, if in addition to the [action] property, a SOAP Action URI is
   encoded in a request, the URI of the SOAP Action MUST be the same as
   the one specified by the [action] property.
