I am happy to put such a statement in the glossary. However, I
think that we should add something (or a placeholder) in the WSA
to talk about it. Maybe just to say what you are saying here.

However, I was wondering if we had actually a requirement about this
before saying "We interpret this as a requirement that the
architecture support late binding."

AC004 and AR004.2 read[1]:

|   AC004
|          does not preclude any programming model.
|          + AR004.2 is comprised of loosely-coupled components and their
|            interrelationships.

I think that this is the one that has been discussed when there were
late binding discussions, but I don't think that it explicitely calls
out for it. Maybe we are missing a requirement then.

Or have I missed something in the requirements document?
