Intents attached to WSDL

The Assembly spec says:
Any service or reference that uses an interface marked with intents MUST 
implicitly add those intents to its own @requires list. [ASM80008]

The corresponding statement in the Policy Spec is not as clear or 
definitive.  So, a few questions:

1. Should this be moved to the Policy Spec?  Or, at least we should have 
an equivalent statement in the Policy Spec.
2. Why isn't there a corresponding WSDL extension for policySets?
3. WS-Policy defines a WSDL extension for WS-Policy.  Thus, users can 
attach policies in WS-Policy syntax to WSDL interfaces.  What should SCA 
do about them?
