Discussion:

C99 added isblank and iswblank to <locale.h> but <locale> does not provide any equivalent.

Moved to Tentatively Ready after 6 votes.

Proposed resolution:

Add to 28.3.3.3.1 [classification] synopsis:

template <class charT> bool isgraph (charT c, const locale& loc);
template <class charT> bool isblank (charT c, const locale& loc);

Add to 28.3.4.2 [category.ctype] synopsis:

static const mask xdigit = 1 << 8;
static const mask blank = 1 << 9;
static const mask alnum = alpha | digit;
static const mask graph = alnum | punct;
