That's the $1,000,000 question :-) Just what capabilities do we need to
represent to meet the needs of management applications using the API ?
So far this thread has mentioned what lifecycle states are possible for
a given domain, and what resource adjustments can be made to a domain.
Its probably unrealistic to come up with a complete set ahead of time, so
we probably need an initial basic set which is expanded over time.
