"Raymonda": loud claps? What's that?

Raymonda does not clap.

She is a princess!

In the last act, Raymonda is presented to royalty, and just think of this now:

You would not expect (Britain’s) ex-Queen Elizabeth to make a loud clap.

It is supposed to be just a slight brushing while your hands and your wrists are angled.

Nureyev brought and demanded strong claps to his version. A lack of understanding of good manners?
