// 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 .
// Based on the Interpreter pattern.
