NEW ISSUE: URI attribute should not be mandatory for bindings

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

TARGET: SCA Assembly Specification, section 1.7 Binding

DESCRIPTION: 
The current description of the uri attribute for a binding says that the
uri attribute is mandatory in case the binding is attached to a
reference in the domain.  


The current wording on line 2300 is :

binding element has the following attributes:
 * uri (optional) - has the following semantic.
  ...
 It is optional for references defined in composites used as component
implementations, but required for references defined in composites
contributed to SCA domains.


As clarified by Mike E.
(http://www.oasis-open.org/apps/org/workgroup/sca-assembly/email/archive
s/200710/msg00059.html) that may not be true.



PROPOSAL:
Remove the requirement for the uri and add the following clarification
paragraph :


Some bindings MAY identify a target endpoint without using the uri
attribute  via usage of some binding specific tags and attributes. In
that case the uri for references in composites contributed to the SCA
domain is OPTIONAL. However such binding definition without uri
attribute MUST uniquely specify a target endpoint, since references
contributed to the SCA domain can't be reconfigured by anything and the
SCA runtime will need enough information to ivoke correctly such
reference. In case the binding relies only on the uri to configure the
target endpoint, the uri attribute MUST be present for bindings for
references contributed to the SCA domain.
