[Bug 4130] Ignorable assertions must be ignored

           Summary: Ignorable assertions must be ignored
           Product: WS-Policy
           Version: LC
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Framework

At the last f2f meeting the WS-Policy WG agreed to add an attribute called
'ignorable' to the WS-Policy assertion syntax.  We think this is a step in the
right direction.  The WG, however, blunted the effect of this change by
allowing the ignorable attribute to be ignored during policy intersection by
allowing two intersection modes one of which honors the ignorable attribute and
the other which ignores it.

We argue this creates a problem as the parties attempting to agree on a policy
alternative may use different forms of the intersection algorithm and come up
with different solutions.  A standard that allows such variation is not very
useful.

We suggest that the policy intersection algorithm be changed so that assertions
marked ignorable are always ignored.
