11.7 Mail Merge Data Source
Source Relationship:
http://purl.oclc.org/ooxml/officeDocument/relationships/mailMergeSource
A document that stores information about a mail merge operation is permitted to contain a Document Settings part (11.3.3) whose relationship item targets the file location of the necessary data source using this relationship.
[Example: Consider a document specifying a mail merge whose data source is located at http://www.openxmlformats.org/data.txt:
<Relationships xmlns="…">
<Relationship Id="rId1"
Type="http://…/mailMergeSource"
Target="http://www.openxmlformats.org/data.txt"
TargetMode="External"/>
</Relationships>
The document’s Document Settings part contains a dataSource element that explicitly references this relationship:
<w:settings …>
<w:mailMerge>
…
<w:dataSource r:id="rId1" />
…
</w:mailMerge>
</w:settings>
end example]
A mail merge data source shall be located external to the package containing the relationships part (expressed syntactically, the TargetMode attribute of the Relationship element shall be External).
