Documentation error?

[spud]

Just glancing at this project for possible future use, and noticed what seems like an issue with the documentation:

// Either get the Code object and read it's code and/or value
$type = $product->getNotificationType();
$code = $code->getCode(); // "03"
$value = $code->getValue(); // "Notification confirmed on publication"

I assume the second line of code should read:
$code = $type->getCode();

Since $code was not defined prior to this line. I haven't dug into the code itself, but that strikes me as probably incorrect.

Apologies if I've misunderstood!
