Placing a section name at the start of a staff

[Anthonys Lists]

Basically, I want to do pretty much what "instrument name" does in a 
score - I want to put the name of the section in front of the start of 
the staff. The problem is, as always, when you use a feature for what 
it's not intended for, you can get unexpected side effects. I've got 
four sections, so that'll mean four \score's. Will I get unexpected 
(read - unwanted) headers between the scores? Basically, if you don't 
notice the section name, you shouldn't realise that the music doesn't 
just flow on.

My other approach to doing this sort of thing is "\stopStaff \cadenzaOn 
... \cadenzaOff \startStaff" but will this suppress things like key 
signature etc at the start of the line? My initial experiments in that 
respect haven't worked, although it seems obvious to me why. But I don't 
want to carry on down that route if it's going to turn into a rabbit's 
warren of tweaks and fixes to get right.

Searching the lsr or googling just points me at loads of stuff about 
"outside staff objects" - not surprisingly since text is normally 
outside the staff - but it leaves me wondering "am I not using the right 
search terms, or is there nothing to find?".

How do other people deal with section names? Especially, how do you do 
it like the score I'm copying - at the start of the line ...
