The RecalcPath trigger specifies that the Directory function token update trigger exists on the drawing page specified by its RefBy_Type child element. It MUST have a DocumentSheet_Type parent element.

A Trigger_Type element with an N attribute value of RecalcPath MUST exist if the web drawing contains a Directory function token, and a RefBy_Type child element MUST exist for every drawing page in the web drawing that has a DocLastSave function token.
