I believe you have to differentiate between accents (up, down or middle)
and overline/underline. The way we use it in the Elsevier journal DTDs
is as follows: accents are always over/under/through one symbol or character.
Overline and underline can be over multiple characters. Default ornament
is a line; other possibilities are ^ ~ { [ and a few more. There are also
styles: all ornaments can be bold, some can double (line, [ () some
can triple, be dashed, dotted. I can provide more details if people wish.
