Multiple Sections
Documents are capable of having multiple sections, where each section can define up to three headers and footers. By default, sections other than the first section inherit the previous header and footer references, unless that section specifies header and footer references.
Consider a two-page, two-section document with only the first section header defined. This document defines one header that is referenced in the first section. The document is represented by the following WordprocessingML:
<w:body> … <w:p> <w:pPr> <w:sectPr> <w:headerReference r:id="rId6" /> … </w:sectPr> </w:pPr> … </w:p> … <w:sectPr> … </w:sectPr> </w:body>
The second section does not explicitly reference a header. Instead, the second section inherits the header from the previous section.
