Actually I want to talk about it a little bit more.

std::message facet is designed after POSIX catopen and catgets

See: 

  http://pubs.opengroup.org/onlinepubs/009695399/functions/catgets.html
  http://pubs.opengroup.org/onlinepubs/009695399/utilities/gencat.html

POSIX defines various rules on how to load message catalogs their
format.

However it is POSIX interface and as you probably
understand Windows does not like such standards
and according it MSDN std::message does nothing:

So as you can see, message facets not so useful
as they may seem...
