Randall,

Thanks for your reply.
I was wondering especially about those "deprecated" properties.. What
happens after several releases? Do you just remove them at that point? If
the expected maximum lifespan of a stack is shorter than the span for which
those "deprecated" properties are maintained, then removing them works. But
what happens if it is longer?

Cheers,
Praveen
