Perhaps the following could be added to the Nested Staff Groups section
of the page
http://www.lilypond.org/doc/v2.18/Documentation/notation/displaying-staves
"By default Piano Staff, Grand Staff and Staff Group can be nested
inside a Choir Staff and any of these can be nested inside a Staff
Group."
perhaps immediately before the sentence "New nested staff group contexts
can be defined."
Thanks for the clarifications, I see what I can reasonably check now.
