+	/// <remarks>
+	///   Use SerializableAttribute to mark classes that do not implement
+	///   the ISerializable interface but that want to be serialized.
+	///
+	///   Failing to do so will cause the system to throw an exception.
+	///
+	///   When a class is market with the SerializableAttribute, all the
+	///   fields are automatically serialized with the exception of those
+	///   that are tagged with the NonSerializedAttribute.
+	///
+	///   SerializableAttribute should only be used for classes that contain
+	///   simple data types that can be serialized and deserialized by the
+	///   runtime (typically you would use NonSerializedAttribute on data
+	///   that can be reconstructed at any point: like caches or precomputed
+	///   tables). 
+	/// </remarks>
