Description Christopher Ferris 2006-12-08 14:04:56 UTC
I believe that it would be most appropriate if the WG scoped its work on the WSDL1.1 element identifiers 
working group note to the specific set of WSDL1.1 policy attachment points defined in the WS-Policy 1.5 - Attachments 

Going further than that would IMO be of marginal value to the WG and would potentially add to the amount of effort 
needed to complete the work. Our primary concern is with using these identifiers 
in the context of policy attachments.
Comment 1 David Orchard 2007-01-17 19:02:22 UTC
I'll note that I think the same problem applies to WSDL 2.0, that is there are components that have designators that are not policy subjects listed in the attachments doc.  

How about the following new paragraph for 3.4.1:
The scope of URI domain expressions for WSDL 2.0 components or WSDL 1.1 elements is limited to the subjects defined in this specification at (ref to Attaching Policies Using WSDL 1.1 and WS-Policy Attachment for WSDL 2.0).  

(note, what happens if somebody puts a URI with an out-of-scope subject, does it fail)  
Comment 2 David Orchard 2007-01-17 19:32:38 UTC
Combining 4045 with 4127 with Editors action 112 ( ( add WSDL 1.1 reference) could yield:

URI domain expressions are used to identify resources that are identified using IRI or IRI References (such as endpoint, message or operation definitions) with which policies can be associated. For example, URI domain expressions can be used to identify WSDL 1.1 definitions, WSDL 2.0 components, etc.  When a URI domain expression identifies multiple resources, ie WSDL 1.1 supports multiple operations with the same name (sometimes called operation name overloading), the Policy applies to all the resources that are identified. 

IRI References for WSDL 2.0 components are defined in Appendix C of the Web Services Description Language (WSDL) Version 2.0 Part 1: Core Language [WSDL 2.0 Core Language]. The following example illustrates the use of URI domain expression with a WSDL 2.0 IRI Reference: 

(01) <wsp:PolicyAttachment>
(02)   <wsp:AppliesTo>
(03)     <wsp:URI></wsp:URI>
(04)   </wsp:AppliesTo>
(05)   <wsp:PolicyReference URI="" />
(06)  </wsp:PolicyAttachment>
In this example, the policy expression at applies to all interactions with the endpoint at 

IRI References for WSDL 1.1 elements are defined in WSDL 1.1 Element Identifiers [ref].

The scope of URI domain expressions for WSDL 2.0 components or WSDL 1.1
elements is limited to the subjects defined in this specification at (ref to
Attaching Policies Using WSDL 1.1 and WS-Policy Attachment for WSDL 2.0). 

Comment 3 Paul Cotton 2007-01-17 22:27:01 UTC
In addition Change the Section 4 as follows:

This section describes a mechanism for associating policy expressions with Web 

service constructs in WSDL 1.1. The mechanism consists of:

- A model for attaching policies to WSDL 1.1 constructs. The model defines:

	- A partitioning of WSDL constructs into service, endpoint, operation and 

message policy subjects.

	- The semantics of attaching a policy to each policy subject.

	- How to combine policies attached to more than one WSDL construct within 

a single policy subject.

- An XML representation of policy expressions attached to WSDL 1.1 constructs. 

- The annotation of such policy expressions as required extensions using the 

WSDL-defined extensibility flag @wsdl:required.

<fix above sentence is the WSDL 2.0 section>

WSDL 1.1 disallows the use of extensibility elements on certain elements and the 

use of extensibility attributes on others. However, the WS-I Basic Profile 1.1 [BP 

1.1] overrules this restriction and allows element extensibility everywhere. 

Therefore, when attaching a reference directly to the WSDL element the policy 

reference SHOULD be attached using wsp:PolicyReference as child element unless it 

is absolutely necessary to maintain the original WSDL 1.1 restriction, in which 

case the @wsp:PolicyURIs attribute MAY be used for the following WSDL elements:

Note that the resolution to 4332 reverses part of this decision.
