 I don't have my notes on it since I left my notebooks at my previous
employer.  My memory is  some of the device manufacturers handled "Set Max"
type commands differently and also interpreted the spec a  differently on
the contents of the mentioned bits and words in ID Device.  The company I
worked for at the time was developing some drivers and was seeing
inconsistencies.  I talked with others at one of the T13 meetings and found
they were seeing similar things.  Anyway, may be a moot issue today.  I know
it was enough at the time that it did make mention in the document and
section (e03107r0 sec. 3.1)  I referred to in my previous post.  Maybe
Mukesh remembers or can answer whether or not it is still an outstanding
issue.  I believe he picked up the PARTIES-2 after myself and Ron Salmon
left.
