Yes.

Any input we can provide to the TAG regarding [2] would be helpful. In my view, the PING questionnaire should:
- focus primarily on privacy
- have a cover note with a relatively short list of questions/issues and some recommended best practices for particular situations
- provide more detail regarding the issues raised by the questions (this is your idea for more of a deep dive/more comprehensive resource)

Agree. Thank you Giri.

Everyone, please provide your feedback on the list or come ready to discuss these points on 3 December 2015.

I don’t have a good answer on how to reword it, but simply being mindful it will be a hot debate is a good first step. I'd love to have a discussion on how we can craft something that satisfies both sides of the pond.
