Please thank them for me if you know who they are :-) I'm sure we will find useful information there. Kieran, could you please have a look when you'll be back at the end of this week, and list the points that you think we don't address correctly yet ? -- Regards, Laurent Pinchart

(v0.53 is for ES2.0, but this chapter should be same for ES1.x / ES2.0) You may / may not find something from here Best regards --- Kuninori Morimoto
