For documents - a full document is equated to a web page.  See WCAG2ICT report.

Otherwise running headers and footer should be made pagination artifacts and the Page Labels feature should be used to add Page numbering including section information to identify pages and sections to assistive technology.  The page label feature is pretty powerful and allows flexibility for different number schemes such as Roman numbers and custom label prefixes.

In general I recommend marking that content as non-artifact content on the first and last page so it does not break up the reading order of content.
