Yes, I have read the spec, several times.

I was not commenting, in particular, on the XPR spec itself, but rather, on the
comments by you in the posting I was replying to, wherein you said things like
"it doesn't make sense to have more than one... <whatever> in a (comm | BBS)
program. It was an observation, pointing out that it might indeed make sense to
have any configuration we can visualize, or even those we have not thought of
yet.
