Multimeasure rests and Fermata
This is an opinion. Where a fermata occurs over a full measure rest, it disappears and the measure is included in a multimeasure rest if there is a full measure rest on either side of the fermata measure. I believe the fermata measure should stand alone with the fermata displayed on it. This should be so regardless of the type of fermata used.
