                                                Schema

Modified Schema validator for TurboGears.

    A schema validates a dictionary of values, applying different validators
    (by key) to the different values.

    This modified Schema allows fields that do not appear in the fields
    parameter of your schema, but filters them out from the value dictionary.
    You might want to set filter_extra_fields to True when you're building a
    dynamic form with unpredictable keys and need these values.

**Messages**

``badDictType``:
  The input must be dict-like (not a ``%(type)s``: ``%(value)r``)

``badType``:
  The input must be a string (not a ``%(type)s``: ``%(value)r``)

``empty``:
  Please enter a value

``missingValue``:
  Missing value

``noneType``:
  The input must be a string (not None)

``notExpected``:
  The input field ``%(name)s`` was not expected.
