Not quite.  For Jinmei's example, Conceptual Sending Algorithm will not 
indicate that P::Y is on-link because the Prefix List of X does not include 
P::Y.  Then, given the statement in our document that says an address 
resolution can only be performed on addresses that are on-link, X cannot send 
the address resolution NS out.  Remember the private email thread we went 
through where I said the Conceptual Sending Algorithm doesn’t really apply to 
ND control messages - this Algorithm is really for data packets.  Your emails 
today have said repeatedly to just send the NS address resolution out.  I hope 
you see the controversy now?
