Not sure exactly. I think it has to at least be partly part of the
spec, because getContext() is part of the API. But I don't know
exactly what the spec has to say about it (of course, you can go read
the spec, it's available at sun, and relatively easy reading, as these
things go :-).
Also, Tomcat is supposed to be the reference implementation of the
spec, so you'd think they'd stick to it pretty closely.

Not really sure on this -- I think there may be some complications in
trying to do this. I have seen some discussion of this on another
servlet-related list I'm on -- servlet-interest, run by Sun. You
might check there -- you can access the archives from:
