There will be some of that too, but I have something more general in mind.

    a b c | \sectionLabel "Coda" d e f |

"Coda" is just an example.  It could be "Intro", "Refrain", "Part 2", etc. It 
could appear anywhere.

I also would like to provide a sane adaptive default for D.S. instructions 
mentioning these labels.  For example, if a user codes \sectionLabel "Outro" at 
the appropriate point of a \repeat segno, I want LilyPond to use "D.S. al 
Outro" without having to be told anything else.  Emphasis: I don't intend to 
try to handle all cases correctly automatically, but to provide a default that 
works for Coda, has a chance of being acceptable for other names, and is at 
least consistent even if it isn't acceptable.

If the user had to code \sectionLabel "CODA" for the sake of the section label, 
then the D.S. formatter would have to recapitalize speculatively to avoid "D.S. 
al CODA".  I might be willing to implement that, but it is less appealing than 
recommending that the user capitalize as "Outro" and use grob properties to 
remap case.

If the user had to code \sectionLabel "OUTRO" for the sake of the section label 
and then had second thoughts about the style, restyling would require a search 
and replace rather than just changing a grob property in a "house style" 
include file.

> I vaguely recall Coda in small caps. Is all caps Gould advice?

In _Behind Bars_, p. 239, all letters are capital and have the same height.  
I'm not knowledgeable enough about fonts to tell whether this is all caps or 
small caps.

SOLO/TUTTI on p. 467 look similar.

Character labels on p. 470 look similar and Gould explicitly calls them "small 
capitals," here, but again all letters have the same height.

TH.  I plan to try enabling small caps and adding the option to transform to 
*lowercase* in text-interface to avoid a larger "C" in "CODA".
