Nope. It's rather assume it is my question which is causing the confusion.
I'll sumbit a new issue which will hopefully result in an answer...

  I think you are getting confused with policy intersection and wire format. WS-SecurityPolicy is an example where the domain has chosen policy assertions that express wire format but that is the choice of the domain. Policy intersection can happen w/o having to express wire formats.

  Thanks... It's a start :-).
  That said it's not a very informative answer. I've had a chance to examine the spec. I'd appreciate an example please. 

  More specifically, given that such policies have no wire manifestations, it's not clear whether
  a requester is required to understand such a policy in order to engage in the communication or not (no intersection is involved).
  In other words, does one have to use wsp:optional to advertize such polices ?

  It's likely I misunderstand few things about the way a requester should behave hence this question.

  WS-PolicyAttachment gives several examples of advertizing policy regardless of any wire manifestations.

              Policy expressions with no wire manifestation 
              
       

  Hello,

  WS-Policy Framework refers to policy expressions which may have no wire manifestations.

  Can someone please explain how such polices should be advertized, giving an example if possible.

  Thanks, Sergey Beryozkin
