There's not a documented way, but a section tag maps to a vector whose
second element is the section's number spec (roughly, a list of
numbers, one for each level of nesting). So, you can use
`delayed-element` like this:
#lang scribble/base
@(require scribble/core)
@title{The Document}
@section[#:tag "sub"]{The Section}
See @(delayed-element
(lambda (r p ri)
(let ([v (resolve-get p ri (make-section-tag "sub"))])
;; Turns '(1) into "(1)" for demo purposes:
(format "~s" (vector-ref v 2))))
(lambda () "x")
(lambda () "x")).
The representation of section information is renderer-specific, but
currently the renderers all use a vector of a least three elements, so
the number spec is always there. Probably that fact should just be
documented and guaranteed forever, although a vector wasn't a great
choice.
