Hi Martin, Whit and others,

sorry for skipping in with what may be a no-brainer.
I didn't realy follow the thread entirely neither
did I look in detail at Martin's code in 'company'.

So, this is just a question in passing:

Is what you are discussing here covering the following
usecase?

"support arbitrary many (independent?) schema extenders"

What I mean by that is the following: people can install
unforeseen combinations of 3rd-party add-on products which
each in turn might want to change or extend a type's schema.
If they are independent that should cause no problem, but:
What if there is a conflict (e.g., two different products -
not knowing of each other - are trying to change or add a
field with the same name/id but intend to use this field for
completely different purposes)? (real world example: quite a
number of products (could want to) mess with the 'Subject'
field.)

How would that be detected?
What would happen?
Are you addressing this at all?

Just a thought ...

Raphael
