Subject: Review of WS-A WSDL Binding

 


As per my action item, here are my comments on [1]. 

1. Section 2 introduces some elements, <wsaw:InterfaceName>,
<wsaw:ServiceName> for refering to WSDL Interface, Service, and Endpoint
components. The same result could be achieved by using the IRI-reference
component designators defined in WSDL 2.0 Part 1, Appendix A. 



These elements have to refer to WSDL 1.1 constructs as well, this and
other reasons (e.g. difficult syntax) we did not have consensus to
recommend to the WS-A WG that they should consider component
designators.

 


2. Section 2 also defines the use of embedding WSDL in <wsa:Metadata>
which indicates that people think it's useful to embed WSDL in other XML
documents. This raises a question about WSDL 2.0. In <include>,
<import>, and @wsdlLocation a location is specified. The spec says this
location should dereference to a WSDL 2.0 document. Should it also be
allowed to derefence to an element in an XML document, e.g. via a
fragment id? This is the case for XML Schema. 



We recall we defined "WSDL 2.0 document" specifically as a
<wsdl20:description> element, which should enable fragment ids to work.
If you think this is no longer the case we should raise it as an issue.

 


3. Section 3.1 defines the <wsaw:UsingAddressing> Extension Element. I
have a question about terminology. Our spec is inconsistent. Sometimes
we say Extensibility element and sometimes Extension element. I suggest
we use Extension element and attribute throughout, rather than
Extensibility.  I think this is purely editorial. I'll make the change
if no one objects. 



Agreed.

 


4. The XML example 4-1 is wrong since it uses <definition> as the root
element. It should use <description> 



Will forward.


5. Section 4.3 defines the use of <wsa:ReferenceParameters> but does not
say how this affects the WSDL 2.0 component model. Does this add a
property to Endpoint? 



Will forward.
