 An \tcode{unordered_set} meets all of the requirements
 of a container\iref{container.reqmts},
-of an allocator-aware container\iref{container.alloc.reqmts},
+of an allocator-aware container\iref{container.alloc.reqmts}, and
 of an unordered associative container\iref{unord.req}.
 It provides the operations described in the preceding requirements table for unique keys;
 that is, an \tcode{unordered_set} supports the \tcode{a_uniq} operations in that table,
