If the argument is optional and has no value, this validator will not be used, so zero values is valid regardless of the lower bound specified. If you want zero values to be invalid, make it a required argument.

This validator will not be checked until all arguments have been parsed.

If this validator is used on an argument that is not a multi-value or dictionary argument, validation will always fail.
