Without reading it all and accepting that a domain is nothing but a data type it has seemed to me a retrograde kind of introspection, even bizarre, to first make relations out of domains (granted, IIRC from other posts, it seems that the SQL standard doesn't depend on the term 'relation'), then turn around and make those relations into data types.   Maybe M$ should be re-thinking all those old pieces this Linq thing is depending on.
