Section 25.3.1 [locale] says:
-4- In the call to use_facet<Facet>(loc), the type argument chooses a facet, making available all members of the named type. If Facet is not present in a locale (or, failing that, in the global locale), it throws the standard exception bad_cast. A C++ program can check if a locale implements a particular facet with the template function has_facet<Facet>().
This contradicts the specification given in section
template <class Facet> const Facet& use_facet(const locale& loc);
-1- Get a reference to a facet of a locale.
-2- Returns: a reference to the corresponding facet of loc, if present.
-3- Throws: bad_cast if has_facet<Facet>(loc) is false.
-4- Notes: The reference returned remains valid at least as long as any copy of loc exists
Remove the phrase "(or, failing that, in the global locale)" from section 22.1.1.
Needed for consistency with the way locales are handled elsewhere in the standard.
