When you create a UDT with the sp_addtype sproc, you can control the Nullability. Later, when you create a table using that UDT as a column's data type, you can also set the nullability. How do these two nullabilies relate to each other? (IE - can I make all my UDT's 'NOT NULL', and then later make a column usings this type allow nulls on table creation?)

Thanks.
