This is the XML Schema for sca-config used by the SCA configuration type specification. An instance of an sca-config document can optionally contain bindings, intents and policySets. These elements described the detailed configuration for how the service should be made available (e.g. as a soap/http Web service). The SCA specifications from OASIS define the binding types which can be included in a bindings document and how intents and policySets can provide detailed configuration for policies. This attribute should be used by extensions to documents to require that the document consumer understand the extension.
