Yes Jean, this is exactly the type of example I was looking for. Thank you!
It should be added to:
https://lilypond.org/doc/v2.20/Documentation/notation/other#index-_005cwith_002ddimensions
and to:
https://lilypond.org/doc/v2.20/Documentation/notation/other#index-_005cwith_002doutline
as a speaking example.
Cheers,
Pierre
