The XML map that is automatically created is assigned the full pathname given by the XMLMAP= option in your SASEXFSD LIBNAME statement. The map file is either reused (not overwritten) if you specify AUTOMAP=REUSE or overwritten by a new map if you specify AUTOMAP=REPLACE. The SASEXFSD engine invokes the XMLV2 engine to create the map and to read the data into SAS.
