Internationalization
====================

Forms are fully internationalized.  The field names, descriptions,
labels, and hints are all automatically translated if they are made
i18n messages in the schema.

Let's take this simple add form...

  >>> print http(r"""
  ... GET /+/addfieldcontent.html HTTP/1.1
  ... Authorization: Basic mgr:mgrpw
  ... """, handle_errors=False)
  HTTP/1.1 200 Ok
  ...

with an error...

  >>> print http(r"""
  ... POST /+/addfieldcontent.html HTTP/1.1
  ... Authorization: Basic mgr:mgrpw
  ... Content-Length: 670
  ... Content-Type: multipart/form-data; boundary=---------------------------19588947601368617292863650127
  ...

Translated
----------

And now the add form in German:

  >>> print http(r"""
  ... GET /+/addfieldcontent.html HTTP/1.1
  ... Accept-Language: de
  ... Authorization: Basic mgr:mgrpw
  ... """, handle_errors=False)
  HTTP/1.1 200 Ok
  ...Felderinhalt hinzuf...
  ...Eine kurz...Titel...
  ...Eine ausf...Beschreibung...
  ...Irgendeine Zahl...
  ...Irgendeine Liste...
  ...hinzuf...
  ...Auffrischen...
  ...Hinzuf...
  ...Objektname...

The same with an input error:

  >>> print http(r"""
  ... POST /+/addfieldcontent.html HTTP/1.1
  ... Accept-Language: de
  ... Authorization: Basic mgr:mgrpw
  ... Content-Length: 670
  ... Content-Type: multipart/form-data; boundary=---------------------------19588947601368617292863650127
