     * the If "FailIfEmpty" is true, the resultobj parameter is used to specify the object returned to fail-json. You can also override the default message 
       using $emptyattributefailmessage (for missing required attributes) and $ValidateSetErrorMessage (for attribute validation errors)
     * Look at existing modules for more examples of argument checking.
