Would copying the doc string of compose-region into the manual do what
you want?  If not, what in that doc string is missing or not explained
well enough?

I don't understand this claim.  You certainly know what the doc string
says, which is definitely not "nothing".

Is this a serious bug report?  If it is, would you please help me
understand what is missing in the documentation, by at least answering
my questions, if not by elaborating some more about the problem?  TIA.
