well the serialiser doesn't see any markup at all, but it sees an empty
node that looks exactly the same as a node that had been placed in the
result tree by <div/>.

what the serialiser sees is some data in the Xpath data model that it
has to write out using XML syntax. The only thing in the data model
that corresponds to  <div></div> is an empty div node and that could
just as easily have come from a literal "<div/>" in the stylesheet.

It has no information on which to make that decision. To do so would
require extending the parser to report the difference and to extend the
data model so as to annotate every empty element whether to be
linearised using /> syntax.
