Since earl:fail is not a class, it is not possible to subclass it, 
without a significant redesign.

However, one could add OWL axioms like

subClassOf(
    restriction( onProperty earl:outome hasValue(my:value) ),
    restriction( onProperty earl:outome hasValue(earl:fail) ) )

I am not convinced that this would be a good move, since it would 
require a greater level of OWL processing than is currently required by 
earl. The current design does allow additional application specific 
information to be included with the earl:Result.
