To clarify, it seems that the message subject level of attachment can
use binding scope:
. wsdl:binding/wsdl:operation/wsdl:input
. wsdl:binding/wsdl:operation/wsdl:output
. wsdl:binding/wsdl:operation/wsdl:fault
These are the things that attaching reliability DA levels and other QOS parameters might enable
specification of two-way operation types which have different reliability requirements in each direction.
