RE: Make implicit structures explicit

["Costello, Roger L." <costello@mitre.org>]

Hi Folks,

Thanks again for the excellent responses.

Recall that I advocated for adding an attribute that indicates the order in which a list of elements are to be evaluated, e.g.,

<aircraft-approach-procedure>
    <transition step="2">Enter glide slope</transition>
    <transition step="3">Correct for wind conditions</transition>
    <transition step="1">Contact control tower</transition>
</aircraft-approach-procedure>

The argument that dissuaded me most powerfully was this simple message from a colleague:

 	What is the benefit of adding @step (a 
	sequence number)? We are not using 
	key punch cards, so we will not drop it.
