This is a good point.  If I look at the latest Policy Attachment spec it has
a long section on WSDL 2.0 attachment with an extensive discussion of Policy
Subjects and Scopes and merging.  I don't think we want to repeat this material
for the external attachment section.  So, how about we add a paragraph that
says something like:

The semantics of associating policies with WSDL 2.0 components using the external
attachment mechanism are exactly the same as if the policies had been attached directly
to WSDL 2.0 components using the mechanisms described in section 5. The possible 
policy scopes are exactly those allowed in section 5.2 and the calculation of effective policies is done in exactly the same manner as described in section 5.4. 

All the best, Ashok
