MJ, the UK CAA are the voice of EASA. If you contact EASA directly they will refer you back to the UK CAA.
It is the job of the UK CAA to interpret the legislation and set policy as it applies to the regulation. I happen to find them very good at helping with such questions and clarifying how the UK CAA will interpret the policy I regard to UK licence holders and UK training facilities.
As the head of Training of a UK ATO I would be foolish to override their statement of policy because I thought I knew better or read it on a Internet forum...
