expression A variable that represents a XmlMap object.
Deleting the XML map will convert all of the XML Lists to generic Lists and remove all of the single-cell mappings (with the data still remaining). In addition, the XmlMap object will be removed from the XmlMaps collection. The map and schema information will be removed from the workbook (it will no longer be persisted in the XLS file and XMLSS). Any references to the deleted object become invalid.
