Hi all,

starting the work on the RDF mapping, I noticed that our spec doesn't
actually add properties to WSDL components, if this requirement from our
charter is to be understood using the formal terms "component" and
"property" from WSDL 2.0. [1] If we add such formalities, the RDF
mapping, for one, would benefit, as it could follow closely the style of
the WSDL 2.0 RDF mapping document [2].

Luckily, it won't mean big changes to our spec. Here's a sketch of what
I think we might add to satisfy this requirement:

In section 2.1:
        When used on an element that represents a WSDL 2.0 Component
        (e.g. wsdl:interface, wsdl:operation, top-level xsd:element
        etc.), the modelReference extension attribute introduces an
        OPTIONAL property {model reference} whose value is a list of
        URIs taken from the value of the attribute. The absence of the
        {model reference} property is equal to its presence with an
        empty value.

In section 2.2:
        When used on an element that represents a WSDL 2.0 Component
        (top-level xsd:element, xsd:complexType or xsd:simpleType), the
        loweringSchemaMapping and liftingSchemaMapping extension
        attributes introduce OPTIONAL properties {lowering schema
        mapping} and {lifting schema mapping}. The value of either of
        these properties is a list of URIs taken from the value of the
        respective attribute. In contrast to the {model reference}
        property, the absence of the {lifting schema mapping} and
        {lowering schema mapping} properties *is different from* its
        presence with an empty value, as mappings on an element must be
        able to override the mappings specified on the type of the
        element.
        
Any comments?

Jacek
