<p>A standard container composed of equivalent keys (possibly containing multiple of each key value) that associates values of another type with the keys. </p>
<p>Meets the requirements of a <a href="tables.html#65">container</a>, and <a href="tables.html#xx">unordered associative container</a></p>
