By default, the plugin loader looks for a class that has one of the
registered prefixes. So, if you pass 'Regex' as the name, and
'Zend_Validate' is a registerd prefix, it finds it. However,
there is no match to a fragment 'Zend_Validate_Regex' with an
*additional* 'Zend_Validate' prefix.
So, either use the short name ('Regex', in your example), or instantiate
the validator:
$element->addValidator(new Zend_Validate_Regex($pattern));

Same problem as above. You now have the prefixes "Zend_Validate" and
"My_Validate" on the stack, and it's prepending whatever you pass with
those prefixes when doing the lookup.

Should work on all elements... but only if they are created through your
form object (i.e., via createElement() or addElement()). If you're
instantiating your elements directly, you'd need to add the prefix path
to all elements individually, as they would have no form awareness until
added to the form.
