According to Clause Annex B [implimits] paragraph 1,
Because computers are finite, C++ implementations are inevitably limited in the size of the programs they can successfully process. Every implementation shall document those limitations where known.
Because Annex Clause Annex B [implimits] is informative, not normative, it should not use “shall.”
Additional notes (May, 2024)
The Annex was editorially switched from "informative" to "normative" in September 2020 with this change description:
[intro.compliance.general, implimits] Cite Annex B normatively.
This change also promotes Annex B [implimits] to a "normative" annex. The existing wording in the annex is already normative in character.
Discussion about the intended normative contents of Annex B is pursued in issue 2891.
