2 Component Model

Component Model

This section describes the conceptual model for WSDL as a set of components with properties, each aspect of a Web service that WSDL can describe having its own property. In addition an XML Infoset representation for these components is provided, along with a mapping from that representation to the various component properties. How the XML Infoset representation of a given set of WSDL components is constructed is outside the scope of this specification.
