+Detail for Marionette Collective message PLMC16
+===========================================
+
+Example Message
+---------------
+
+ 'hello' does not look like a numeric value
+
+Additional Information
+----------------------
+
+When MCollective receives an argument from the command line like port=fello it consults the DDL file to determine the desired type of this parameter, it then tries to convert the input string into the correct numeric value.
+
+This error indicates the input you provided could not be converted into the desired format.
+
+You'll usually see this when using the 'mco rpc' command to interact with an agent. This is usually a fatal error, the request will not be sent if it does not validate against the DDL.
