Each validator has a list of messages, which you can see in the docs. 
For instance, Regex(r'^\w+$', messages={'invalid': 'Please enter just 
letters and numbers'}).

You get a single exception for invalid input, that contains all the 
exceptions for the individual fields.  Probably you'll find it easiest 
to use exc.unpack_errors() to get a list of messages.

on the schema, filter_extra_fields=True.
