The page +headers in a document are often the same from page to page, with only small +differences in content, such as a section and/or page number. Such a header +is also known as a *running head*. + +In book-printed documents, where pages are intended to bound on the long edge +and presented side-by-side, the header on the right-hand (recto) pages is +often different than that on the left-hand (verso) pages. The need to support +this difference gives rise to the option to have an *even-page* header that +differs from the default *odd-page* header in a document. + +A page footer is analogous in every way to a page header except that it +appears at the bottom of a page. It should not be confused with a footnote, +which is not uniform between pages. + +In WordprocessingML, a header or footer appears within the margin area of +a page. With a few exceptions, a header or footer can contain all types of +content that can appear in the main body, including text and images. Each +section has its own set of headers and footers, although a section can be +configured to "inherit" headers and footers from the prior section. + +Each section can have three distinct header definitions and footer +definitions. These apply to odd pages (the default), even pages, and the +first page of the section. All three are optional. + +For brevity in the discussion below I will occasionally use the term *header* +to refer to either a header and footer object, trusting the reader to +understand its applicability to either type of object. + + +Header and footer parts +----------------------- + +Each header or footer definition is a distinct part in the WordprocessingML +package. + +A header/footer part is related to the document part by a relationship entry. +That relationship is referenced by a section in the document by its rId key. + +A default document will contain no header or footer parts and no +`w:headerReference` or `w:footerReference` elements in its `w:sectPr` +element. + + +Research TODO +------------- + +1.
