RE: PMD discussion

Part of the reason for the overlap is the selection of objectives.  We
should not penalize the PMD vendors for that.

Multiple options confuse the market when they overlap and the set of 5 
options contains substantial overlap.

It is legitimate for informed people to disagree on complex issues and for 
us to have difficulty converging on the short list of PMDs.

But everyone should be absolutely clear that the shorter the list is the 
better both for market growth and for ease of completing the specification.
