	I agree we've passed a point of no return in the use of Identify 
Message Out.  I've no objection to clarifying the expected behavior in 
SIP.  I do feel a bit cautious about accepting your request verbatim for 
two reasons:

1) It violates my (admittedly primitive) grasp of SAM's layering 
philosophy to specify the behavior of an interface signal in the protocol 
document...seems the natural home would be SPI.

2) I can envision a number of other disastrous cases that could result 
|from broken interface hardware.  My own experience has been that trying 
to specifically address any but the most common failure modes is 
counterproductive.  I'd like to understand more clearly why this 
particular hardware failure should be singled out.

	So none of this is to say "Yes" or "No" at this time.  I'll 
certainly raise the question at the appropriate time and include or 
exclude the text you've requested according to the voice of the committee 
membership.  In the meantime, it's on the queue of issues.  Thanks for 
taking the time to propose it and give us some background.
