True.  I've used this as a step between build (msi expansion) and load.

> How do you validate field assignments in your application, Michael?  I need to be able to do something like the following:

So far only link fields (where I usually typo).  Field types are known,
so this could be done for other fields.  However, it wouldn't give quite
the same assurance as it would be different code (pypdb doesn't depend
on Base).  So I'm not sure if this would be good enough for you.
