                                                         If set to 1 (default) — all Meridian client links check empty mapped property values to determine if the value was set that way (Empty) or if they have never been set (Null). If a property was set to Empty, the link empties the corresponding document property. If set to 2 or greater — the links force all mapped document properties to empty regardless of whether the file properties are Empty or Null. If set to 0 — the check is not performed. Note:
