[pmwiki-users] how to intersect groups with pagelist?

Given two groups X and Y, is it possible to pagelist the intersection of 
the two groups, that is all pages that are in X and in Y, where only the 
{$Name} part counts to determine the intersection?  And is it possible to 
list the complementary set, that is all pages that are in X but not in Y?
Or maybe pagelist isn't the best way to do this?

----
example:

X = {p1,p2}
Y = {p1,p3}
(:pagelist intersect group=X,Y:)   --> p1
(:pagelist complement group=X,Y:)  --> p2
(:pagelist complement group=Y,X:)  --> p3

TIA,
