Subject: RE: [sca-bpel] Issue 14: we forgot intents


 

I've made some proposed changes to the spec as part of this resolution.  You can find them here.

 

I ran into a problem with directly reusing the XSD definition of @requires from the assembly specification.  The problem was that our extension to WS-BPEL is defined as follows:

 

   <extensions>

      <extension

         namespace="http://docs.oasis-open.org/ns/opencsa/sca-bpel/200801"

         mustUnderstand="yes" />

   </extensions>

 

And, unfortunately, WS-BPEL does not allow multiple namespaces to be associated with a single extension.

 

In the version that I have uploaded, I’ve just created a sca-bpel:requires attribute and reused SCA’s definition of sca:listOfQNames.  I’ve also added a normative reference to the policy spec for its exact syntax and semantics.

I like it. No reason to create a new attribute (it is a global attr decl

in SCA schema). This means WSDL and BPEL would use the same extension

attribute with the same semantics.
