+// Details: MI common code class. Command argument class. Arguments object
+// needing specialization derived from the CMICmdArgValBase class.
+// An argument knows what type of argument it is and how it is to
+// interpret the options (context) string to find and validate a matching
+// argument and so extract a value from it .
+// The CMICmdArgValBase objects added to *this ListOfN container belong
+// to this container and will be deleted when *this object goes out of
+// scope.
+// To parse arguments like 'thread-id ...' i.e. 1 10 12 13 ...
+// If vbMandatory argument is true it takes on the (...)+ specification
+// otherwise assumed to be (...)* specification.
+// Based on the Interpreter pattern.
+// Gotchas: None.
