+1 If it turns out that standardizing such a mechanism does become something of great utility, we can easily add it in a future version without breaking anything. Plus we'd have some real use cases on which to base the design.

Folks, here's my opinion on BINDINGS-107, I'd appreciate your comments/opinions. 

The main purpose of having JMS and JCA binding elements in the definitions file is to allow a single JMS/JCA application to be accessed from several SCA references or services without having to duplicate all the details of connection and operation mapping.  That's primarily due to the fact that there's no standard service definition for JMS/JCA applications.  Typically for service bindings, the information is going to be specific to each exposed service so I would expect such sharing to be mainly but not exclusively used for references. 

There's no functional reason why we require this mechanism. If we remove it from the spec it doesn't reduce the capability of the bindings, it just means that SCA runtimes would possibly need to provide their own way of managing sharing of such information outside of the standard definitions.  Given that this is not a portability/interop requirement I'd say its not that high a priority to be standardised.  If we feel that the additional complexity that this brings to the JMS and JCA bindings specs is not justified, then I don't feel particularly strongly about removing it.
