:-) This allows multiple defaults.

I was trying to set with (:input default ..... 
Is this already implemented? 
If not I would vote/request for such feature.

True,  the change was a testing, there needs to be a better check/option for 
separator and cleaning space.

Assuming the multiple input to be csv style text.
A better option: (for PHP 5 >= 5.3.0)

  $t = is_array($InputValues[$name]) ? 
       $InputValues[$name] :  str_getcsv($InputValues[$name]);
  $opt[$checked] = in_array(@$opt['value'], 
        preg_replace(array('/^\s/', '/\s$/'), '', $t)) ?
        $checked : false;
