+    can never depend on server version, they cannot depend on anything
+    related to the environment. They can also only depend on a set of
+    fields in the table itself. They cannot depend on other tables and
+    cannot contain any queries and cannot contain udf's or similar.
+    If a new Item class is defined and it inherits from a class that is
+    allowed in a partition function then it is very important to consider
+    whether this should be inherited to the new class. If not the function
