類std::locale::id提供的語言環境方面實現特定的標識。 std::locale::facet來自每個類必須有一個公共的靜態成員的類型std::locale::id和它實現的方面，每個std::locale對象保持一份索引他們的ids的.

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.

}

Output:

has_facet<myloc, myfacet> returns true
