Wraps this handler as a "top level" handler, which will inject a SpacTraceElement
(representing the current input or the "EOF" signal)
to any exception is thrown by this handler when calling its step or finish methods.

In response to an error thrown and caught from a downstream consumer, this handler may modify the exception on its way back upstream. Used by the "spac frame" transformer.
