Yes, I agree that the docs read this way. The point under discussion
here was the use of a <Context/> docBase within server.xml - it's
necessary in order to disambiguate the use of a <Context/> to a
specific application.

I don't understand "may be ignored". Either docBase is ignored in this
situation, or it isn't.

I'm afraid I haven't encountered this behaviour described in the docs.
I'd be grateful of a reference to it. Where documentation is missing,
or where further clarity is required (as suggested by repeated
user/developer mistakes), what is the procedure within Apache for
helping make this happen?

That suggests that you've encountered cases where it is reasonable for
the docBase and the context's xml file name to differ. However, the
ambiguity in the use of docBase (re. above), and the double deployment
problem that you mention, makes it difficult to solve this problem -
worse if the use of <Context/> taken away as an option.
If it's agreeable to the guys that have responded so far, then I'd
like to get this discussion onto a thread of its own so that the
subject reflects the discussion and mail headers refer to a specific
topic. If you'd like to continue the discussion about <Context/> that
we have started here, then please give me a little time to post this
question as another message on this list - referring to this thread in
the archives to avoid repetition.

Agreed!
Thanks,
Paul.
