How about at the end of section 2.2.1?  I don't think I have all the 
spec-ese right here, but how about adding something along the lines of the 
following:
[[
Operation Name Mapping Requirement.

The following requirement is intended to ensure that a received message can 
be uniquely mapped to a corresponding wsdl:operation.

Consider all Interface Operation components specified in the {operations} 
property of that Interface component.  Further consider all Message 
Reference components specified in the {message references} properties of 
said Interface Operation components.  Further consider all said Message 
Reference components that have the same value for their {direction} 
property (i.e., either the token "in" or the token "out").  If the {message 
content model} property of any of these Message Reference components has a 
value of "#any", or if more than one of these Message Reference components 
has a value of "#none", or if the top level elements of the XML element 
declarations specified by the values of the {element} properties of these 
Message Reference components are not unique when considered together, then 
either:

(a) the {features} property of the Interface component MUST contain a 
Feature component, having a wsdl:required attribute with a value of true, 
that unambiguously identifies the mechanism that a message sender is 
required to support in order to enable the message recipient to 
unambiguously determine the name of the wsdl:operation that is intended to 
be associated with the received message; or

(b) the "element information item" for the Interface component MUST contain 
an extension element (i.e., an element that is not in the wsdl: namespace), 
having a wsdl:required attribute with a value of true, that unambiguously 
identifies the mechanism that a message sender is required to support in 
order to enable the message recipient to unambiguously determine the name 
of the wsdl:operation that is intended to be associated with the received 
message.
