I'm with Heather on this.
 
I would like to see us separate the "how" of accomplishing the goals from
the actual goals ad requirements. This lends clarity to the goals and
requirements. I understand that we haven't done this in other sections of
the requirements document, however I support doing this. It is appropriate
to have the discussion of how we want to accomplish meeting the requirements
and the model(s) discussion will enter into this. 
 
So +1 to Heather's disagreement with 18.1.5 and 18.2.5

Hao,
We tried to keep this at the level of the goals and requirements for
manageability. I think that creating a management model may be part of
ACCOMPLISHING the goals/requirements, but I don't think that its a first
class requirement. Putting a model in the goal begs the question of what
kind of model and how is it expressed, etc., and I think its too detailed
right now. We would be imposing HOW to satisfy the requirement in the
requirement. 

In addition, I"m not sure we can create a standard model for instances. The
instance level stuff should be specific to instances. If we need to
express/save relationships between instances we probably need to define that
at a Web Service Architecture implementation level. I also thing that
lifecycle control is at the architecture implementation level, not web
service instance level.

So, I disagree with 18.1.5 and 18.2.5.

hi, Zulah,

Good work. It reads very well.  I'd like to add some more. See comments

Hi All,

Here is a proposed rewording of AC018 from Heather and Zulah.

Comments?
