The reason I create the subclass on-the-fly was that it was a quick way 
to allow the None value to be set on a field in a Create surrogate.

I agree that having this kind of ability in Field rather than hacked 
into Entity would be smarter though.  Perhaps it already supports this 
and I didn't look closely enough :)   I'll investigate and see what I 
discover.
