A derived template class that describes an object that can serve as a collate facet of a given locale, enabling the retrieval of information specific to a cultural area concerning string sorting conventions.
template<Class CharType>
    class collate_byname : public collate<CharType> {
public:
    explicit collate_byname(
        const char* _Locname,
        size_t _Refs = 0
    );
    explicit collate_byname(
        const string& _Locname,
        size_t _Refs = 0);
protected:
    virtual ~collate_byname( );
};
Parameters
- _Locname 
 A named locale.
- _Refs 
 An initial reference count.
Remarks
The template class describes an object that can serve as a locale facet of type collate<CharType>. Its behavior is determined by the named locale _Locname. Each constructor initializes its base object with collate<CharType>(_Refs).
