Hello Olivier, Not 100% sure, but I tend to favor option 2) as well to avoid changing to many things (imagine you would have to refactor lot's of parsing code, lot's of comparison statements with option 1). And option 2 isn't shocking me at this point. Thank you for all this serious work, this is very much appreciated by us and our customers. On Thu, Feb 2, 2012 at 10:08 AM, Launchpad Bug Tracker <
