Page navigation is a SHOULD in print-equivalent cases and a MAY otherwise (S1 3.4.1.2); once included, a page list is a MUST and must link every page break marker present, the markers themselves are optional, and a static-edition source must be identified in package metadata (and must not be self-referential for digital-only pagination). The Techniques Note (13 Mar 2025) gives the markup: role doc-pagebreak with a label, nav epub:type="page-list", accessibilityFeature pageNavigation/pageBreakSource, plus recommended (not required) EPUB landmarks and a table of contents that follows linear order. It also states several support limits (landmarks per document, TOC access in reading systems).
