Greetings David,

Quoting Mark (the man through whom the scandal cometh!) in the very
first mail in this thread,

Obviously not all markups are titles, but all titles are
markups, right?

Fair point. However I don't remember LilyPond having the ability to
print footnotes (or proper endnotes, for that matter) *at all*.

Perhaps we're looking at this the wrong way, and that would be because
"markup" is such a vague term in LilyPond. Basically, anything and
everything can be done through markups (as Mark sensibly reminded us,
even "titles" are actually markups).

My point is, (speaking from a purely user-perspective, btw): your
suggestion seems valid to me, but worded in a manner (differentiating
"titles" and "markups") that is a bit confusing -- since, from what I
gather, what you're really trying to distinguish is
"official-markup-that's-defined-as-a-title" and
"user-custom-markup-that-isn't-meant-to-be-regarded-as-an-official-title"
(well, I can understand the need for a single word :)

As you said, we need to have different levels of hierarchy, and
ideally, a scheme where we could add as many levels as we'd like.
-> Perhaps we could use HTML naming? h1-spacing, h2-spacing,
h3-spacing, hn-spacing,... etc? (where h1 would be the book title, h2
the piece title, etc.)
-> Perhaps we could give a number as a parameter? markup-1-spacing,
markup-2-spacing, etc. (and possibly add something like
markup-unprioritized-spacing, like, for endnotes/footnotes) ? Anyway,
as you said yourself, this may very well be a GLISS discussion
already.
