Roger, I wouldn't mind numbering if there was a pre-processing step that sorts the steps according to their numbers, and removes the numbering attributes :) Cheers, Dimitre On Thu, Apr 10, 2014 at 4:45 AM, Costello, Roger L. <costello@mitre.org> wrote: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. /Roger _______________________________________________________________________ XML-DEV is a publicly archived, unmoderated list hosted by OASIS to support XML implementation and development.
