Hello I'd like to ask few questions (I'm assuming the requestor initiates the intersection) : 1. why Lax intersection mode produces duplicates for A & B ? 2. why the provider's F is in the effective policy produced by the lax intersection mode ? My understanding of the lax mode is that it accepts an ignorable provider's assertion only if it understands it, and in this case it does not, so it tshould be dropped 3.Why D is in the effective policy produced by the lax intersection mode ? Provider does not know anything about D so the effect of requester putting D in the effective policy can be undefined - 4. Given 3 should the intersection fail ?
