equals()method on MQeAttribute and its subclasses in Version 1.2.7 (and earlier versions), has been renamed as
isAcceptable()
An MQeAttributeRule now ships with the product.
You should now extend your attribute rules from this class instead of MQeRule.
All methods on MQeAttribute and its subclasses, which used to take an MQeRule object as one of its parameters, now take an MQeAttributeRule object instead.
