Subject: [PATCH] added: to Space:        bool HasValue(const wchar_t * name,
 const wchar_t * value);        bool HasValue(const wchar_t * name, const
 std::wstring & value);        bool HasValue(const std::wstring & name, const
 wchar_t * value);        bool HasValue(const std::wstring & name, const
 std::wstring & value);        useful when testing whether a value is in a
 list (or in simple table too)
