class locale::id;

Класс std::locale::id обеспечивает реализацию конкретных идентификации языка грань. Каждый класс, производный от std::locale::facet должен иметь открытый статический член типа std::locale::id и каждый std::locale объекта ведет список граней он реализует, индексированный по их ids.

Original:

The class std::locale::id provides implementation-specific identification of a locale facet. Each class derived from std::locale::facet must have a public static member of type std::locale::id and each std::locale object maintains a list of facets it implements, indexed by their ids.

    std::cout << "has_facet<myloc, myfacet> returns " << std::boolalpha
              << std::has_facet<myfacet>(myloc) << '\n';
}

Вывод:

has_facet<myloc, myfacet> returns true
