Error in validation hooks documentation

[juanvaccarezza]

Hi, The function signature is incorrect.

In the example says: (rest of the code omitted for simplicity)

...
def check_document(document):
....
def check_item(item):
....

but in order to work should be:

...
def check_document(document, tree):
...
def check_item(item, document, tree):
...

Best regards, Juan

I can generate a PR if you like.
