Parser exception trace output

Use a Trace node to produce details of exceptions that occur when the message parser is started.

The following figure shows an extract of the output that might be generated by a Trace node that has the Pattern property set to a value that represents a structure that includes the exception list tree.

The exception shown occurred when the message parser was invoked.
