+SECoP Issue 8: Groups (under discussion)
+========================================
+
+Proposal
+--------
+
+Modules as well as parameters may have a property "group".
+If the client has the possibility to group modules and/or
+parameters, it should use this information for grouping.
+
+Groups must start with uppercase letters.
+
+The "group" property may contain colons (':') as separator,
+in order to construct a hierarchy of more than one level.
