Sorry for having been unclear. I can at least clarify that part: the 
term "problematic" was to explain why Chris and myself thought it was 
safer to mark the external frame "at risk".

But the question was really to try to clarify what are external frames.

For the remainder of your reply: I have to think about it and try to 
connect it with my request for clarification. I will come back to you
