it's almost like in controllers, where you assign variables to the view, 
with the only difference that you have to remove them again after you 
rendered the viewHelper content.


public function render($what, $as,...) {
	//...
	$processedContent = ...;

	$this->templateVariableContainer->add($as, $processedContent);
	$output = $this->renderChildren();
	$this->templateVariableContainer->remove($as);

	return $output;
}
