@tonydspaniard I suggest:

```
        array(
            'content' => '...',
            'header' => 'This is caption header and this ROCKS!',
            'headerOptions' => array(...),
            'description' => 'This is the caption description and this also ROCKS!',
            'descriptionOptions' => array(...),
        ),
```

Maybe `captionHeader` and `captionDescription` as option.
