Description:
The current binding.ws specification
makes no normative statements which relate to WS-Policy.
However, there are clearly parts of
the specification that do relate to WS-Policy and it also the case that
for Web services, WS-Policy is the defined
policy language.
I believe that the binding.ws specification
should make a definite statement about support for WS-Policy
as a policy language.
Note that this does not imply a requirement
for the support of any specific concrete policies that might be
expressed in the WS-Policy language.
It does imply that a binding.ws implementation cannot fail merely
because it encounters WS-Policy constructs.
It also implies that IF a binding.ws instance seeks to advertise
policies then it must do so using WS-Policy.
Proposal:
Add a normative statement that a binding.ws
implementation must support the WS-Policy specification:
This support takes the following forms:
a) accepting WS-Policy statements in
supplied WSDLs
b) advertising applied policies in generated
WSDLs
c) accepting WS-Policy statements in
PolicySets
d) for the purposes of policy matching
between references and services, the binding.ws implementation
must follow the policy intersection
rules of WS-Policy
The support DOES NOT imply that a binding.ws
implementation must support any particular concrete policy
expressed using WS-Policy.
Detailed text:
Add a new section 2.10, as follows:
2.10 Support for WS-Policy specification
A binding.ws implementation MUST support
the WS-Policy specification and MUST:
a) accept WS-Policy statement in any
supplied WSDLs
b) advertise any policies applied to
a service using the WS-Policy language
c) accept WS-Policy statements in SCA
policySets
d) use the WS-Policy policy intersection
rules when matching policies between a reference and a service
[BWS20038]
Note that the requirements relating
to WS-Policy do not mandate that the binding.ws implementation has to
support any specific concrete policies.
The requirements are that the WS-Policy language itself must be
supported and that the presence of WS-Policy
constructs cannot be used to reject an SCA artifact.
Yours, Mike.
