/**
 * Zend_Form_Decorator_ViewScript
 *
 * Render a view script as a decorator
 *
 * Accepts the options:
 * - separator: separator to use between view script content and provided content (defaults to PHP_EOL)
 * - placement: whether to append or prepend view script content to provided content (defaults to prepend)
 * - viewScript: view script to use
 *
 * The view script is rendered as a partial; the element being decorated is
 * passed in as the 'element' variable:
 * <code>
 * // in view script:
 * echo $this->element->getLabel();
 * </code>
 *
 * Any options other than separator, placement, and viewScript are passed to
 * the partial as local variables.
