There's been a lot of discussion on obsoleted documents from the IPC 
and George Frank recently touched on the military documents.  If this helps, 
and probably like many of you, I got the pleasure of going through a military 
audit about two years ago.  One of the issues that they were firm on with 
military documents was "Correct, Current, and Approved."  They made it clear 
that all amendments, updates and revisions must be incorporated.  If a 
customer asked you to manufacture to Rev. A and the document was at revision 
C, you'd have to say, "I'm sorry, there is no such document.  But, I can use 
this other document."  This would exclude existing government contracts which 
have their own set of rules by definition of the contract.
	I suppose you could get by using any obsolete document as a reference 
as long as you don't "certify" to that document.  Maybe incorporate all the 
requirements into an internal specification and reference that.
	One other note, when our internal documents reference any industry or 
military standards, we omit the revision level with the document number and 
say "current revision of..."  I would guess that most companies do this to 
save on work later.
