Hi Hao:

  I think blocking UpdateCapsule = interface is enough for Capsule in RAM.  QueryCaps= uleCapabilities can still be used to test capsules before delivering by different sources= .

For this patch, it only&nb= sp;affects UpdateCapsule(). Do we need to upd= ate the
behavior for QueryCapsuleCapabilitie= s() as well?
