NEW ISSUE: Replacement of binding types

["Peshev, Peter" <peter.peshev@sap.com>]

TARGET: SCA Assembly Specification

DESCRIPTION: Each binding defined in the SCA specification should have a
bindingType. 
For example the current bindingType of the binding.jms is defined as :

<bindingType type="binding.jms" alwaysProvides="jms"
mayProvide="atLeastOnce atMostOnce ordered conversation"/>

Some vendors support more features that are not part of the standard on
which the binding is based so it should be mentioned how it is possible
to extend the existing specs. For wexample whether the standard
bindingType that is defined within a binding spec, could be replaced (by
adding supported intents) or the recommended solution is to define an
extension for the whole binding -- i.e.  binding.sap.jms.


PROPOSAL: Provide functionality and sample for such extension.
