The number has to be introduced by its label. A bare a/b is not evidence of a
Drucksachennummer and reading one as such produced real misreadings: a page
header Seite 2 / 4 became reference 2/4, im Verhältnis 2/3 became 2/3,
and Stand 11/2024 became 11/2024 — each a document identity that does not
exist. Structure cannot separate them, because 11/2024 is a perfectly
well-formed reference; only the label can. With no labelled number this returns
undefined and the caller abstains, which is the honest answer.
