>> So a collection ends when you find rdf:nil as the value of rdf:rest
(no matter what else might be in the description); rdf:nil is an atom,
if you like, but it's not an *element* of the collection unless its the
value of rdf:first on some subcollection before the first rdf:nil value
of an rdf:rest. <<

So this clears up the whole problem of disjoint lists both having an
element in common (i.e. rdf:nil), right?
