For those who don't know who Danny is, that is Danny Coward --
specification lead for the servlet spec.
I did ask. He agreed that it's not spec'd but that it makes sense to give
the included servlet a sense that it is talking to the "same" request that
the calling servlet is, even though it's not technically true. The only
change that the original servlet can make when it "accesses" the request
is to set or remove attributes, so an included servlet should be able to
as well.
