Thanks.  Sorry it took me so long to get to this; I've been down with the 
flu all last week.

I've fixed the typos, but I'm curious about the del operations.  Are you 
seeing problems in practice, or are you just concerned about this?  If I 
recall the state machine correctly, it should *not* be possible for the del 
to happen twice unless something is wrong with the behavior of the 
RecordType or RecordManager objects.  I specifically did *not* check for 
attribute existence because I wanted to be able to notice the errors.

So if you are seeing errors from this in practice, I'd like some more 
detail so I can figure out what's wrong.  Thanks.
