Not sure how you got from "fixed set of disclosures" to "do not enable 
the definition of user defined disclosure"? A fixed set of disclosures 
sets the operations that an application will support, doesn't say 
anything about what a user may or may not do in that context.

Yes, updates in views, according to Date are not correctly supported in 
the SQL standard, much less any known SQL product. (Date, 8th edition, 
page 300, ftnt 2)

I think you may be missing the difference between a disclosure, which 
set the parameters for what can be done, as opposed to what a user does 
in that context.

The TMDM for example sets forth a data model and provides rules for 
processing instances of that data model. It in no way limits what users 
can say in the context of that data model, save for staying within the 
bounds of the data model.

I don't envision other disclosures being any different in that respect.

Closer? Farther away?

Hope you are having a great day!
