Well, no, it can't -- because you don't have any validators associated
with it. You *have* made it required, but because you don't explicitly
set a NotEmpty validator, there's no way to set the message.
Add a validator, and add messages, as I showed you in my previous
message; if you are only testing for NotEmpty, and want a custom
message, add the validator explicitly. Add your validators just like
you've added filters in your example:

You need to create elements somehow.
$form->addElement('text', 'name', array(
'required' => true,
'filters' => array('StringTrim', 'StringToLower'),
'label' => 'Name',
'description' => 'A unique name for the action, letters only.',
'validators' => array(
array('NotEmpty', true, array('messages' => array('custom error message'))),
),
));

I can't speak to the performance of the I18N components as I've done no
benchmarking with them, but they wouldn't likely add that much overhead
to your application.

$form->addElement('text', 'name', array(

'filters' => array('StringTrim', 'StringToLower'),
'label' => 'Name',
'description' => 'A unique name for the action, letters only.',
'validators' => array(
