RE: re[2]: More on getObjectExtent()

We heard back from Dieter and Don. It would be good to find out if
others agree with them.

Assuming they do agree, this thread is a non-issue.

Benoit (et al) --

As I'm understanding this thread, there is no need to create and resolve
an issue here.  I.e., your question about our (historical) intent was
answered by Dieter and confirmed by Don, and that seems to be the end of
it.  Is that accurate?

On the other hand, if you wants to challenge that as a wrong decision,
there is an issue to be generated.  Or if he wants clarifying language
...ditto...  (In the latter case, could you please propose a place and
approximate language?)

By the way, Benoit -- thanks for all of the spec feedback that you're
generating!
