Subject: rx has nothing for `explicitly numbered group construct'

Hello,

rx.el in 23.1 through 24.50 has nothing for a regexp notation
of "explicitly numbered group" construct incorporated in 23.1.

Maybe would it be something like,

`(group 'NUM ...)' or `(group-n NUM ...)'

for `\(?NUM: ... \)', where NUM is an integer?

Regards,
