hi, Heather and Zulah,

What if I change the "management model" to "conceptual management model"?

This simply says that you need something so all the operations, events and
so on can hang together using this thing called "conceptual management
model".  It does not say "how".

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?
