Re: Issue BINDINGS-113

BINDINGS-113 states:

Description: 

BWS20006 says -- 

"When an invocation is made using
an SCA reference binding with the wsdl.service form of wsdlElement, the
SCA runtime MUST use exactly one port from the set of available ports for
the reference (with port selection on a per-invocation basis permitted)."

This is, at the very least, untestable.
But I think it is also a pointless stmt. If the selection is made on a
per-invocation basis, and if *an* invocation can involve only one endpoint
(which I think it does), then this is a redundant statement. It can never
be violated, but definition. 

Proposal: 

Remove BWS20006. 

The intention of this statement is to
say for a reference, when the binding points at a WSDL service, which could
have more than one available port, that the reference can use any of those
ports for any invocation, but that it must not use other ports that are
not included in the service description.   I think we still need this
rule, and I believe that it should be testable, so I'm not keen on removing
the statement.  Perhaps rewording it to: 

"When an invocation is made using
an SCA reference binding with the wsdl.service form of wsdlElement, the
SCA runtime MUST use one of the set of available ports for the reference
[BWS20006]. Note that this allows the port that is used to vary for each
invocation."
