Ok. I got what Chris was referring to. Thanks. But it's immaterial who consumes the policy first, the actual client who start wiring that info into the client runtime or the broker acting on the client behalf or some other entity  to the point of this issue. All of them are consumers in a sense that they do the intersection.

The point of this issue is that the provider needs to be aware that marking the assertion as wsp:ignorable does not guarantee it will be ignored for intersection purposes in all the intersection scenarious...The section actually says that but I just suggest to make that message a bit more stronger...

I thought there was a common agreement on adding a statement like this before, has anything changed ? 

Thanks, Sergey

  +1 to Chris. 

   

  Policy intersection (and enforcement) will be externalized in many cases - by PEP, for example.

  I didn't say provider. I said not client. There is a distinction.
