+  Saves the mode of the content type: I = internal, H = hidden
+
+  An internal content type is one that is not user-defined and maintained
+  internally. A content type should be made internal under the following
+  two conditions:
+  1) The object type needs to take advantage of content type services
+  (i.e., versioning, categorization, lifecycle, workflow) that are already
+  implemented in CMS.
+  2) The content type cannot be explicitly registered to a content section.
+  The Template content type is one such internal content type.
+
+  A hidden content type is one that cannot be used directly but other content
+  types can extend from it. Also, it is a legit parent for UDCTs.
