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

AC018 Enables the management of web services

AC018.1 Ensures that implementations of the Web Services Architecture
are manageable.
AR018.1.1 Define a base set of standard metrics for architectural
components and their interactions accompanied by guidelines for
measurement.

Hi All,

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