Yes, it is. See this section of the manual:
http://framework.zend.com/manual/en/zend.form.elements.html#zend.form.elements.validators
and look for the note entitled 'Validation Context'.
Basically, you'll create a custom validation class, and have its
isValid() method accept a second argument, $context, which will be the
array of values being validated in the form. Add the prefixPath for that
validator to your config file, and then you'll be able to use it in your
validations.
