Subject: [ISSUE 143] There are no conformance statements in section 8.5 (CD03) -Proposal
8.5 SCA Binding
The SCA binding element is defined by the following schema.
<binding.sca />
The SCA binding can be used for service interactions between references and services contained within the SCA Domain. The way in which this binding type is implemented is not defined by the SCA specification and it can be implemented in different ways by different SCA runtimes. The only requirement is that any specified qualities of service are implemented for the SCA binding type. The SCA binding type is not intended to be an interoperable binding type. For interoperability, an interoperable binding type such as the Web service binding is used.
An SCA runtime MUST support the binding.sca binding type. [ASM90005]
A service definition with no binding element
specified MUST use the SCA binding. [ASM90006]
<binding.sca/> only has to be specified explicitly in override cases,
or when a set of bindings is specified on a service definition and the
SCA binding needs to be one of them.
If a reference does not have a binding subelement specified, then the binding used MUST be one of the bindings specified by the service provider, as long as the intents attached to the reference and the service are all honoured. [ASM90007]
If the interface of the service or reference is local, then the local variant of the SCA binding will be used. If the interface of the service or reference is remotable, then either the local or remote variant of the SCA binding will be used depending on whether source and target are co-located or not.
If a reference specifies a URI via its @uri attribute, then this provides the default wire to a service provided by another Domain level component. The form of the URI MUST be as follows:
· <component-name>/<service-name> [ASM90008]
