In sca-binding-webservice.xsd / <binding.ws> the specification of the endpoint/port should be optional

In sca-binding-webservice.xsd / <binding.ws> the port or endpoint attribute should be optional. An application developer should be able to specify that he wants a Web Service binding on a composite service or reference without specifying the WSDL endpoint or port, which will be specified later by a system administrator for example, or derived from default settings and (on a service) from where the composite is actually running.

I will raise this issue to the OSOA specfication workgroup.

<complexType name="WebServiceBinding">
<complexContent>
<extension base="sca:Binding">
<sequence>
<any namespace="##other" processContents="lax" minOccurs="0" maxOccurs="unbounded" />
</sequence>
<attribute name="port" type="anyURI" use="required" />
<anyAttribute namespace="##any" processContents="lax" />
</extension>
</complexContent>
</complexType>

should be changed to:

<complexType name="WebServiceBinding">
<complexContent>
<extension base="sca:Binding">
<sequence>
<any namespace="##other" processContents="lax" minOccurs="0" maxOccurs="unbounded" />
</sequence>
<attribute name="port" type="anyURI" use="optional" />
<anyAttribute namespace="##any" processContents="lax" />
</extension>
</complexContent>
</complexType>
