//  DDLSAX2Handler: Implementation of the SAX DocumentHandler interface
//
//  This is kind-of sneaky-cheating.  Basically it ignores all elements except
//  File elements, and displays attributes up to the name attribute because that
//  is the only one it cares about at this time.  Later we would need a mechanism
//  to exclude and include sections based on the configuration if we proceed with
//  that level of selectivity.
//
//  The file name is passed back to DDLParser via SetDDLFileName in order to
//  process this list of files later.
