--- Comment #4 from Christophe Strobbe <c_strobbe-fdo at yahoo.co.uk> ---
Adding some background information from the PDF Association's "Tagged PDF Best
Practice Guide: Syntax" (Version 1.0, June 2019):

Subchapter 3.7.1: Header and footer content

Page headers and footers are usually placed automatically as a function of
pagination. As such this content is not part of the reading-order of the
document and is not considered to be “real content.

Subchapter 3.7.2: Page numbers

Page numbers must be marked as artifacts in marked-content sequences with a
property list entry Pagination (see ISO 32000-1, Table 330 – Property list
entries for artifacts) property).
Accessible page enumeration is enabled through use of the Page Labels (ISO
32000-1, 12.4.2). It is semantically appropriate to have Page Label values
match the visible page number.
