Michael: just to be clear :) I fully agree with the following facts
- BLD is not core
- a profile mechanism should be developed
...although I think the statement "core is a profile of BLD" will lead
to problems (ie a dialect should always be considered as a development
of Core, even if in this case we are considering extricating core from
BLD). 

Dave: would something like
- BLD includes a notion of class membership
- Core does not include a notion of class membership
...solve your objections? 
Or would that depend on other differences between Core and BLD? 
Or is there a requirement for 2 dialects: one with a strong notion of
including data models (say BLD) and a profile thereof that excludes such
notions?
