+(* Take the type constraint on Record into account *)
+
+Definition Type1 := Type.
+Record R : Type1 := { p:Type1 }. (* was accepted before trunk revision 11619 *)
+
+(* 
+Remarks:
+
+- The behaviour was inconsistent with the one of Inductive, e.g.
+
+  Inductive R : Type1 := Build_R : Type1 -> R.
+
+  was correctly refused.
+
+- CoRN makes some use of the following configuration:
+
+  Definition CProp := Type.
+  Record R : CProp := { ... }.
+
+  CoRN may have to change the CProp definition into a notation if the
+  preservation of the former semantics of Record type constraints 
+  turns to be required.
