RE: Strawman list of goals for WSAWG

WS Architecture fans,
 While I agree with Steve's contention that simplicity is not a
measurable goal, I do think that should not be a litmus test for a goal.
I think these goals, apart from being ultimate requirements that output
from the WG must satisfy, should also serve as reference points while we
deliberate on different approaches to architectural issues. One approach
might be to rephrase these immeasurable/intangible goals like
simplicity, extensibility as guidelines to be followed in design, not as
goals in themselves.

One of the goals (AG005) mentions simplicity and ease of use, but I
don't believe those are necessarily architectural qualities but instead
are implementation qualities. I have seen complicated architectures
implemented in simple and easy-to-use products, and I have seen simple
architectures implemented in cumbersome and hard-to-use products. Have
AG005 as an architectural goal is also impossible to measure. I suggest
we eliminate it.
