Description:

The way in which the XSD is constructed
for the wireFormat and operationSelector is incorrect and causes problems
for
other specifications (particularly Bindings
specs).

Currently, wireFormat and operationSelector
are declared as follows:

<element
name="wireFormat"
type="sca:WireFormatType"/>
<complexType
name="WireFormatType"
abstract="true">
     
  ...
</complexType>

<element
name="operationSelector"
type="sca:OperationSelectorType"/>
<complexType
name="OperationSelectorType"
abstract="true">
        ...

The problem here is that the element
declarations for wireFormat and operationSelectoor are not declared "abstract",
which
then requires them to be described in
specifications that don't provide support for concrete types that extend
wireFormat or
operationSelector.

This is not the way in which other extension
points are declared - compare with Binding:

<element
name="binding"
type="sca:Binding"
abstract="true"/>
<complexType
name="Binding"
abstract="true">
        ...

In this case, only a specification which
provides an extension to the Binding type (such as binding.ws) needs to
describe the
Binding element, since abstract elements
cannot be used.

Proposal:

Change the wireFormat and operationSelector
element declarations to use "abstract":

<element
name="wireFormat"
type="sca:WireFormatType"
abstract="true"/>
<complexType
name="WireFormatType"
abstract="true">
     
  ...
</complexType>

<element
name="operationSelector"
type="sca:OperationSelectorType"
abstract="true"/>
<complexType
name="OperationSelectorType"
abstract="true">
