If your first argument is something like Script, you might want to make
it of type symbol? instead. I actually have a syntax sanitizing patch
in limbo where unquoted words are not accepted as strings. It is not
going to make it into 2.18, but I don't promise I won't push it at some
later point of time.
It is probably worth considering to make properties of type context-mod?
(potentially optional), then you can write the argument as
\with {
voice = "vc1"
source = "Ms. 2"
author = "Urs Liska"
date = "2013-06-06"
}
Of course, you might get unsets and overrides and reverts slipped in
which you would want to weed out again, but list? is also prone to
permitting a lot that you don't want to see.
