The underlying reason that intersect didn't work in the previous example
is that it uses node-identity, as opposed to content-equality (as with
fn:deep-equal). Creating a copy of a node changes its node-identity and
"disconnects" it from the underlying document (an input document is
immutable just as variables are immutable).
