/**

* 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
|
|
* - viewModule: module that view script is in (optional)
|
|
*
|
|
* 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, viewScript, and viewModule are passed to
|
|
* the partial as local variables.
