This package provides an interface to Saxon tracing and debugging capabilities.
The package was originally created by Edwin Glaser.
The package includes three tracing modules that can be optionally selected:
TimedTraceListener. These all receive notification of the same events,
but select and format the events in different ways to meet different requirements.
Other events are notified through the
TraceListener interface that
are ignored by tracing applications, but may be of interest to debuggers.
