Constraints and Inheritance

I am 
not confident that organizations will want their constraints to be applied to 
specializations. In the case where a constraint is really an "authoring" 
guideline, there is no reason to apply the constraint to specializations: the 
content models for specializations created by the organization are inherently at 
the right level of specificity for the task.

 

As 
Erik said during the call: there is no current way, given limitations of our 
implementation technologies, to have constraints "automatically" inherit down 
the specialization hierarchy. So there is no efficiency benefit to be had in 
saying that constraints apply down the specialization hierarchy. In fact, it 
just creates work for specialization/constraint maintainers, trying to maintain 
consistency up and down their specialization hierarchy.
