headerReference (Header Reference)
This element specifies a single header which shall be associated with the current section in the document. This header shall be referenced via the id attribute, which specifies an explicit relationship to the appropriate Header part in the WordprocessingML package.
If the relationship type of the relationship specified by this element is not http://schemas.openxmlformats.org/officeDocument/2006/header, is not present, or does not have a TargetMode attribute value of Internal, then the document shall be considered non-conformant.
Within each section of a document there can be up to three different types of headers:
First page header
Odd page header
Even page header
The header type specified by the current headerReference is specified via the type attribute.
If any type of header is omitted for a given section, then the following rules shall apply.
If no headerReference for the first page header is specified and the titlePg element is specified, then the first page header shall be inherited from the previous section or, if this is the first section in the document, a new blank header shall be created. If the titlePg element is not specified, then no first page header shall be shown, and the odd page header shall be used in its place.
If no headerReference for the even page header is specified and the evenAndOddHeaders element is specified, then the even page header shall be inherited from the previous section or, if this is the first section in the document, a new blank header shall be created. If the evenAndOddHeaders element is not specified, then no even page header shall be shown, and the odd page header shall be used in its place.
If no headerReference for the odd page header is specified then the even page header shall be inherited from the previous section or, if this is the first section in the document, a new blank header shall be created.
[Example: Consider a three page document with different first, odd, and even page header defined as follows:
f290aae3-2d0e-46b2-9a84-7e59757bc879
This document defines three headers, each of have a relationship from the document part with a unique relationship ID, as shown in the following packaging markup:
<Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
…
<Relationship Id="rId2" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/header" Target="header1.xml" />
<Relationship Id="rId3" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/header" Target="header2.xml" />
<Relationship Id="rId5" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/header" Target="header3.xml" />
…
</Relationships>
These relationships are then referenced in the section's properties using the following WordprocessingML:
<w:sectPr>
…
<w:headerReference r:id="rId3" w:type="first" />
<w:headerReference r:id="rId5" w:type="default" />
<w:headerReference r:id="rId2" w:type="even" />
…
</w:sectPr>
The resulting section must use the header part with relationship id rId3 for the first page, the header part with relationship id rId2 for all subsequent even pages, and the header part with relationship id rId5 for all subsequent odd pages. end example]
