1298. Missing specialization of ctype_byname<char>

The <locale> synopsis in 30.2 [locale.syn] calls out an explicit specialization for ctype_byname<char>, however no such specialization is defined in the standard. The only reference I can find to ctype_byname<char> is [locale.facet]:Table 77 — Required specializations (for facets) which also refers to ctype_byname<wchar_t> which has no special consideration.

Is the intent an explicit instantiation which would use a slightly different syntax? Should the explicit specialization simply be struck?

Proposed resolution:

30.2 [locale.syn]

Strike the explicit specialization for ctype_byname<char> from the <locale> synopsis

template <class charT> class ctype_byname;
template <>            class ctype_byname<char>;  // specialization
