Subject: [NEW ISSUE] Assembly Specification should state that Services andReferences typed by Local interface cannot have Bindings

Raiser:                Mike Edwards

Target:                SCA Assembly Specification - sca-assembly-1.1-spec-cd01-rev2.doc


Services which implement Local interfaces can only be called from References of Components that are running
in the same operating system process as the service provider component.  (Lines 2423 - 2425).

Given this, it is hard to see what purpose a Binding would serve if attached to either the Service or to the Reference
involved in such a Wire.  There are no obvious transport protocols or wire formats that can be used to influence
the way in which the wire is implemented.  A Binding in these circumstances cannot serve any useful purpose.


Forbid the attachment of a Binding to services and references which are typed by a Local interface.

Add the following after line 2426:

<service/> and <reference/> elements which are typed by a Local interface MUST NOT contain <binding/> child elements
(applies to service and reference elements of componentType, constrainingType, component and composites).

Yours,  Mike.
