This element specifies the information which shall be used to establish a mapping between the parent structured document tag and an XML element stored within a Custom XML Data part in the current WordprocessingML document.
If this element is omitted, then no XML mapping shall be associated with the current structured document tag. If the parent structured document tag is of type rich text or document part gallery, then this property shall be ignored.
If this element is present and the parent structured document tag is not of a rich text type, then the current value of the structured document tag shall be determined by finding the XML element (if any) which is determined by the attributes on this element. If this information does not result in an XML element, then the application can use any algorithm desired to find the closest available match. If this information does result in an XML element, then the contents of that element shall be used to replace the current run content within the document.
[Example: Consider the following structured document tag:
XML
Copy
<w:sdt>
<w:sdtPr>
<w:dataBinding w:xpath=”/root/name/first” … />
<w:text/>
</w:sdtPr>
<w:sdtContent>
<w:r>
<w:t>old text</w:t>
</w:r>
</w:sdtContent>
</w:sdt>
