+Example of what I mean by Unrestricted in the last comment.
+
+using System;
+using System.Security;
+using System.Security.Permissions;
+
+[assembly: PermissionSet (SecurityAction.RequestOptional,
+Unrestricted=true)]
+[assembly: SecurityPermission (SecurityAction.RequestOptional,
+Infrastructure=true)]
+
+public class Program {
+
+	static public int Main (string[] args)
+	{
+		return 0;
+	}
+}
+
+Once compiled only the PermissionSet is present in the metadata (as
+the patch does), because the SecurityPermission is irrevelant in an
+Unrestricted permission set.
+
+
+Unless of course the other permissions are non-CAS permission. In this
+case they must still be processed separately. So...

+using System;
+using System.Security;
+using System.Security.Permissions;
+
+[assembly: PermissionSet (SecurityAction.RequestOptional,
+Unrestricted=true)]
+[assembly: SecurityPermission (SecurityAction.RequestOptional,

+
+public class Program {
+
+	static public int Main (string[] args)
+	{
+		return 0;
+	}
+}
+
+Would have a both a demand and a noncasdemand entries (also working
+with the patch).
