<id> (Unique ID)

This element specifies a unique numerical ID for the parent structured document tag. This ID shall be persisted through multiple sessions (i.e. shall not be changed once specified).

If multiple structured document tags specify the same decimal number value for the @id attribute, then the first structured document tag in the document shall maintain this original ID, and all subsequent structured document tags shall have new identifiers assigned to them when the document is opened.

If this element is omitted, then the parent structured document tag shall have a new unique identifier assigned to it when the document is opened.

example: 
<w:sdtPr>
  <w:id w:val="8775518"/>
  …
</w:sdtPr>

This set of properties specifies via the @val attribute on the <id> element that the ID for the parent structured document shall be 8775518 (subject, of course, to the conflict management and resolution discussed above). ]
