* Form Rule class for the Joomla Platform.
* @package Joomla.Platform
* Method to test if two values are equal. To use this rule, the form
* XML needs a validate attribute of equals and a field attribute
* that is equal to the field to test against.
* @param SimpleXMLElement $element The SimpleXMLElement object representing the <field /> tag for the form field object.
* @param mixed $value The form field value to validate.
* @param string $group The field name group control value. This acts as as an array container for the field.
* For example if the field has name="foo" and the group value is set to "bar" then the
* full field name would end up being "bar[foo]".
* @param JRegistry $input An optional JRegistry object with the entire data set to validate against the entire form.
* @param JForm $form The form object for which the field is being tested.
* @return boolean True if the value is valid, false otherwise.
* @throws InvalidArgumentException
* @throws UnexpectedValueException
