I've seen this differentiation before--static objects are used as points
of reference for dynamic objects, and make the foreground/background
division easier for applications.
I've heard a scenario (not a particularly good one) go something like: I'm
a traveling salesman and have negotiated a deal with a client and want to
print out the changed contract. I look at all of the static objects in my
vicinity to find something I recognize as a printer, or failing that, ask
another static object who must know where the printer is.
In this example, the static attribute allows a foreground/background
differentiation to take place, underscoring the architectural "lived" from
the fluttering "living," which supposedly reduces "location discovery"
I'm not convinced that this dramatically reduces location discovery, for
there are probably a zillion other protocols available for finding the
Admittedly, there are various other ways of accomplishing the same thing.
An "expires" tag in some ways does what a static/dynamic attribute might
strive to do.
Bill Mitchell recently noted that "everything is dynamic, if you have the
