It's pretty much the same as the fact that using an undefined property does not
trigger any error message. You put the undefined property into the props
alist, and then it's never checked by the engraver, so there's no issue.
The list parser (found in scm/fret-diagrams.scm, fret-parse-marking-list)
silently ignores any unknown codes in a fret-diagram-verbose list. I can see
that it would be not too much effort to add an error message. I will put it on
my to-do list.
Thanks,
Carl
