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.

 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
