In general s/error condition/edge case/ here as constructs with fully
specified behaviours are no longer errors.

A couple of problems this causes are:

1) It results in code that is difficult to understand without knowing
   all the edge case possibilities;
2) there are many applications (I mentioned spam filters, but search
   engines are another example) that want to only have a light weight
   parser and would be forced to have a much fuller one.
