[Simple-support] how to determine where in the xml file/stream an exception is thrown?

[Lawrence S. <Law...@vt...>]

If I throw an exception in a "setSomething" method, how can I  
determine where in the XML stream the exception occurred (e.g. the  
StAX cursor location)?  Is this info available in a Validate method?

In SAX this is the Locator object and its getLineNumber() and  
getColumnNumber() methods.
