"This isn't just a "shall" for IPC, it's also a requirement for many other 
standards-bodies, external auditors and certification bodies etc. who want to 
see details of the revision history on any drawing."

True, of course.  But the discussion was started to ask what shall 
future "shalls" require.    Most of the current requirements are just carried 
over from the days of - what was that stuff called? - oh, paper.  If the IPC 
wants to write a standard that is relevant moving forward, it's time to not just 
do what we've always done and examine the best way using new tools.

I can say with certainty (since we're already using it) that if the new IPC 
standard requires explcit ECN history on a drawing rather than a reference to 
complete database information, we will ignore the standard.  We have a 
business to run.

(James, I hope that didn't come off like a shot at you)
