Demonstrated crosswind and flaps

A question regarding "demonstrated crosswind", if I may?

I know that, in past discussions about demonstrated crosswind, answers as to exactly how it is proven have been pretty vague. E.g. there doesn't seem to be any requirement to use one particular method of landing (wing down vs crab).

But is there a requirement that full flap should be used, as per a "normal" landing?

The reason I ask is because of some comments on this thread, regarding landing a BE76 in 20kt crosswind.

The demonstrated crosswind for this type is 25kt, so the crosswind we are discussing is well within the demonstrated abilities of the aircraft. Yet several posters have suggested using partial, or no, flap.

Would the test pilot have used full flap in demonstrating the 25kt crosswind in the BE76?

I have, in the past, used less than full flap in strong crosswinds, but I'm talking about crosswinds well in excess of that "demonstrated" by the manufacturer (e.g 20kt+ in a C152, which has a demonstrated crosswind of 12kt, and starts getting a bit tricky above 17-18kt).
