Niklas, I agree with your observation.

Fortunately, the Ravenscar guide is currently being adapted to ISO formatti=
ng so that it eventually becomes searchable in their archive. So there may =
be an opportunity to correct some typos and to also polish this part of the=
 text. I was proposing other corrections and I have already pointed them to=
 your remark as well.

Cheers,
Jorge.
