When embedding other Message descriptions, the type name may be relative (e.g. "Point32") if it is in the same package; otherwise it must be the full Message type (e.g. "std_msgs/String"). The only exception to this rule is Header. NOTE: you must not use the names of built-in types or Header when constructing your own message types.
e.g. geometry_msgs/Point[] param
