Empty DS output params show empty `<item>` element in XML

A bug in 2.2, submitted by nickdunn on 04 January 2011

Output params are now visible in the param pool. When a DS output param is empty its value is actually an array with one item: an empty string:

array(1) {
  [0]=>
  string(0) ""
}

This results in XML like:

<ds-test>
    <item handle="" />
</ds-test>

This is remedies by checking array length and its first value:

class.frontendpage.php line 452

if (is_array($value) && !(count($value) == 1 && empty($value[0]))) {

There might be a more elegant way but I’m too tired to recall.
