Decorating Zend Developer Zone

If you're in the mood for design patterns, my article, Decorating with External Data has just been published on Zend Developer Zone and runs through an example of using the Decorator.
I'm really interested to see it get a bit of a kicking from those who really know their design patterns, so if you're one of those people please let me know of anything I should or should not do in the comments here or at DevZone.
