Basically any number or code that has some validation mechanism available
or some common formatting is eligible for inclusion into this library.

These modules generally do not provide background information on the meaning
and use of the specified numbers, only parsing and handling functions.

Interface
---------

All modules implement a common interface. For example for ISBN validation:

    >>> from stdnum import isbn
    >>> isbn.validate('978-9024538270')
    '9789024538270'
    >>> isbn.validate('978-9024538271')
    Traceback (most recent call last):
        ...
    InvalidChecksum: ...

Most of these modules implement the following functions:

 * `validate()`
    validate the correctness of the passed number and return a compact
    representation of the number invalid numbers are rejected with one of the
    exceptions from the stdnum.exceptions module
 * `compact()`
   return a compact representation of the number or code this function
   generally does not do validation but may raise exceptions for wildly
   incorrect numbers
 * `format()`
   return a formatted version of the number in the preferred format this
   function generally expects to be passed a valid number or code

Apart from the above, the module may add extra parsing, validation or
conversion functions.

Requirements
------------

The modules should not require any external Python modules and should be pure
Python. The modules are developed and tested with Python 2.7 and 3.6 but may
also work with older versions of Python.
