*
+ * @ingroup sequences
+ *
+ * @tparam _Alloc Allocator type.
+ *
* Note that vector<bool> does not actually meet the requirements for being
* a container. This is because the reference and pointer types are not
* really references and pointers to bool. See DR96 for details. @see
* vector for function documentation.
*
- * @ingroup Containers
- * @ingroup Sequences
- *
* In some terminology a %vector can be described as a dynamic
* C-style array, it offers fast and efficient access to individual
* elements in any order and saves the user from worrying about
