externalMapping - what is it?

[Spies, Brennan]

Does anyone know the specifics of what is/how to use the ‘externalMapping’ Ant task attribute (or –em command line option) listed in the Axis 2.0 1.1 documentation?   BTW, the Option Reference table on this page (http://ws.apache.org/axis2/tools/1_1/CodegenToolReference.html) is missing entries for a few of the command line options that are cross-referenced by the Ant Task Reference table.     Brennan Spies Sr. Programmer Analyst Shared Application Services
