Subject: Implemented ErrorMultiplexer as primary error handler *
 ErrorMultiplexer is derived from both xercesc::ErrorHandler and
 xalan::ProblemListener * registers itself as XalanTransformer's ErrorHandler
 and ProblemListener * distributes captured errors and warnings to all
 registered ErrorMultiplexer::Receiver instances ** ErrorCapacitor implements
 the ErrorMultiplexer::Receiver interface and as such registers itself in a
 given ErrorMultiplexer instance ** ErrorMultiplexer reduces the different
 xalan and xercesc internal error classifications into either warnings or
 errors * this was implemented to make it possible to easily differentiate
 between warnings and errors ** previously warnings were treated as errors **
 ErrorCapacitor ignores warnings and only captures errors ** WarningCapacitor
 will be implemented to handle warnings during XSLT processing
