A zero-length string is a real value. Whether or not you consider
it to be an error, an unspecified value, or an explicitly specified
value (the value when displaying the form might NOT be an empty
string, it might be 'No Middle Initial' or the original value from
the database record you're editing) depends on the variable,
what it means, and the application.
