One last comment before I make a change...

In the current way you mentioned it, there is a hierarchy.

But one thing I was thinking about adding was an option where both UNSUPPORTED 
and PARSE exceptions are caught.  Not sure it is needed, but at one point, I 
remember thinking about that. That would still be hierarchical, but now I have 
the create a 0.5.  That's my only concern about having an enum.
