I feared that that might be the case.  Ideally, then, the code needs to
be rewritten, since the limitation is unhelpful and serves little, if
any, purpose.  However, since I do not have the capability to write
such code myself, I merely mention it as an "in an ideal world..." sort
of comment.

I am unclear about what you mean by an "ordinary mark".  The
implication of what you say seems to be that a RehearsalMark and an
"ordinary mark" can be anchored to the same barline - which sounds just
like what I am trying to do.

That is an idea I hadn't thought of, and sounds like an excellent
suggestion.  But after experimenting with it, I have not managed to
keep a fermata centred over the barline whilst having a longer text
mark left-aligned on or near the barline.  So far, then, I can't see a
clear solution to what I wanted to do.
