info "(sed) Addresses overview" says:

   An address range is specified with two addresses separated by a comma
(',').  Addresses can be numeric, regular expressions, or a mix of both.

The extension is not how to write two addresses (since POSIX already
requires several commands such as 's' to do so), but that GNU sed
extends the set of commands that take two addresses (where POSIX only
requires the command to take 1).

I think the information you are requesting is already present in the
manual, so it is now a judgment call on whether it can be improved; are
you volunteering to write a patch?
