I think that recovery from errors in this class should be
imlementation-selectable, possibly with a specified default.  That way,
a processor could be used where you really want to recover and proceed,
as in a browser, and also where you want to use a different strategy.
The alternative would presumably be to throw an exception which could be
handled in some way that would allow the processor to continue if
desired.  This would give the same result, and would offer a way to give
the user a notification about the error.
