Yes I noticed that about the SVA document draft I have. Anyway found the directives!
Enterprise - Automotive Industry - List of Directives on Motor vehicles
A little light reading!
I would imagine for the testers to be able to do their job things will have to be fairly easy to understand. Also as it appears they intend to stop SVA on the 28th and start IVA on the 29th with possibly only 2 days training, therefore I cant think its going to be massive changes.
