An instance of this part type contains information about each of the editing sessions performed on the parent workbook at the worksheet level (worksheets added and rearranged in each session).

A package shall contain at most one Shared Workbook Revision Headers part. If it exists, that part shall be the target of an implicit relationship from the Workbook (12.3.23) part.

[Example: The following Workbook part-relationship item contains a relationship to the Shared Workbook Revision Headers part, which is stored in the ZIP item handout revisions/revisionHeaders.xml:

<Relationships xmlns="…">
  <Relationship Id="rId9"
    Type="http://…/revisionHeaders"
    Target="revisions/revisionHeaders.xml"/>
</Relationships>

end example]

The root element for a part of this content type shall be headers.

[Example: revisionHeaders.xml contains the following:

<headers xmlns:r="…" guid="{233BEE23-EB5C-4542-905D-0230EFFED88B}"
  diskRevisions="1" revisionId="4" version="3">
  <header guid="…" dateTime="…" maxSheetId="4" userName="…" r:id="rId1">
    <sheetIdMap count="3">
      …
    </sheetIdMap>
  </header>
  …
  <header guid="…" dateTime="…" maxSheetId="4" userName="…" r:id="rId3">
    <sheetIdMap count="3">
      …
    </sheetIdMap>
  </header>
</headers>

end example]

A Shared Workbook Revision Headers part shall be located within the package containing the relationships part (expressed syntactically, the TargetMode attribute of the Relationship element shall be Internal).

A Shared Workbook Revision Headers part is permitted to have explicit relationships to the following parts defined by ISO/IEC 29500:

• Shared Workbook Revision Log (12.3.17)

A Shared Workbook Revision Headers part shall not have any implicit or explicit relationships to other parts defined by ISO/IEC 29500.
