2. The specs do not adequately address support for discovery.  If  
anything, they make discovery very difficult because policy  
attachment is all over the place and the roll up is to the levels of  
finer granularity rather than the service level where most people  
would expect to find it.  Information expressed as policies will  
likely form an important set of the search criteria when looking for  
services (more typically, looking for the business effects that  
result from the service interaction [2]) and there is no guidance  
(and seemingly no consideration) on how such information can be  
effectively used for discovery or any other function besides message  
level protocols.

[2] Are the "business effects", i.e. what happens when you interact  
with a service, supposed to be expressed as part of "capabilities and  
requirements" covered by WS-Policy?  My initial read was yes, but am  
I reading too much into it?    Again, supporting consumer policies so  
you have something with which to intersect services policies seems to  
be important in the current context.
