Re: [sca-bindings] sca:endpointReference versus wsa:EndpointReferencefor WS Binding

Hi Luciano,

As I recall we were forced into doing this to resolve a limitation with
XML Schema and the use of "xsd:any" leading to a "unique particle
attribution" error.

Is there a particular

without extending it, instead of just referencing the

directly ? 

  

  Here is the snipet from the ws
binding
xsd :

  

  <complexType
name="WebServiceBinding">

          <complexContent>

             
<extension base="sca:Binding">

             
    <sequence>

             
        <element name="endpointReference"
type="wsa:EndpointReferenceType"

             
                 minOccurs="0"
maxOccurs="unbounded"/>

             
        <any namespace="##other" processContents="lax"

             
             minOccurs="0"
maxOccurs="unbounded"/>

             
    </sequence>

             
    <attribute name="wsdlElement" type="anyURI"
use="optional"/>

             
    <attribute ref="wsdli:wsdlLocation" use="optional"/>

             
</extension>

          </complexContent>

      </complexType>

  

  This requires composites to have the
following when configuring the ws binding. Note that although
endpointReference
is an element defined from sca namespace, we still need to use the
child
elements based on the wsa namespace.

  

           
      <binding.ws wsdlElement="http://helloworld#wsdl.binding(HelloWorldSoapBinding)">

           
         <endpointReference>

           
            <wsa:Address xmlns:wsa="http://www.w3.org/2005/08/addressing">http://localhost:8085/services/HelloWorldWebService1</wsa:Address>

           
         <endpointReference>

           
      </binding.ws>
