+<h3><a name="multi_index_container">
+Class template <code>multi_index_container</code>
+</a></h3>
+
+<p>
+This is the main component of Boost.MultiIndex. A <code>multi_index_container</code>
+is a container class template holding a compile-time user-defined list of
+<a href="indices.html">indices</a>. These indices provide different interfaces
+for the management of the elements of the <code>multi_index_container</code>. By itself,
+<code>multi_index_container</code> only provides basic functionality for construction
+and for access to the indices held.
+</p>
+
+<p>
+A <code>multi_index_container</code> type is instantiated with the type of the
+elements contained and a non-empty
+<a href="../../../../libs/mpl/doc/refmanual/forward-sequence.html">
+<code>MPL Forward Sequence</code></a> specifying which indices conform the
+class.
+</p>
+
+<p>
+For convenience of use, all public methods and types of the first index
+specified are inherited by <code>multi_index_container</code>. This also includes global
+operators and functions associated with the index (vg. comparison and
+<code>swap</code>.)

+In the descriptions of operations of <code>multi_index_container</code>, we adopt the

+</p>
+
+<h4><a name="instantiation_types">Instantiation types</a></h4>
+
+<p>
+<code>multi_index_container</code> is instantiated with the following types:
+<ol>
+ <li><code>Value</code> is the type of the elements contained. <code>Value</code> must be
+ <code>Erasable</code> from <code>multi_index_container</code>.
+ </li>
+ <li><code>IndexSpecifierList</code> specifies the indices that the
+ <code>multi_index_container</code> is composed of. It must be a non-empty
+ <a href="../../../../libs/mpl/doc/refmanual/forward-sequence.html">
+ <code>MPL Forward Sequence</code></a> (and, preferrably,
+ an <a href="../../../../libs/mpl/doc/refmanual/random-access-sequence.html">
+ <code>MPL Random Access Sequence</code></a>) of index specifiers. For
+ syntactic convenience, the
+ <a href="indices.html#indexed_by"><code>indexed_by</code></a>
+ MPL sequence can be used.
+ </li>
+ <li><code>Allocator</code> must be an allocator of <code>Value</code> objects
+ satisfying the associated C++ requirements at <b>[allocator.requirements]</b>.
+ The following relaxations to the standard requirements are allowed:
+ <ul>
+ <li>Non-equal allocator instances are supported: swapping two non-equal
+ instances must not throw any exception.
+ </li>
+ <li>For every type <code>T</code>,
+ the type <code>Allocator::rebind<T>::other::pointer</code> can be any
+ kind of random access iterator, provided that it is explicitly constructible from
+ the literal <code>0</code> (standing here as the null pointer) or from any
+ <code>p</code> of type <code>T*</code> pointing into an area allocated by
+ some instance of <code>Allocator</code> or some other allocator type rebound
+ from <code>Allocator</code>. A <code>pointer</code> constructed from
+ <code>p</code> shall dereference to <code>*p</code>.
+ </li>
+ </ul>
+ </li>
+</ol>
+Indices of a given <code>multi_index_container</code> instantiation cannot have
+duplicate <a href="indices.html#tags">tags</a>, either within a single
+index or in two different indices.

+Although the exact definition of <code>ctor_args_list</code> is

+<h4><a name="serialization">Serialization</a></h4>
+
+<p>
+<code>multi_index_container</code>s can be archived/retrieved by means of
+<a href="../../../serialization/index.html">Boost.Serialization</a>.
+Boost.MultiIndex does not expose a public serialization interface, as this
+is provided by Boost.Serialization itself. Both regular and XML
+archives are supported.
+</p>
+
+<p>
+Each of the indices comprising a given <code>multi_index_container</code> contributes
+its own preconditions as well as guarantees on the retrieved containers. In describing
+these, the following concepts are used. A type <code>T</code> is <i>serializable</i>
+(resp. XML-serializable) if any object of type <code>T</code> can be saved to an output
+archive (XML archive) and later retrieved from an input archive (XML archive) associated to
+the same storage. If <code>x'</code> of type <code>T</code> is loaded from the
+serialization information saved from another object <code>x</code>, we say that
+<code>x'</code> is a <i>restored copy</i> of <code>x</code>. Given a binary predicate
+<code>Pred</code> over (<code>T</code>, <code>T</code>), and objects <code>p</code>
+and <code>q</code> of type <code>Pred</code>, we say that <code>q</code>
+is <i>serialization-compatible</i> with <code>p</code> if
+<blockquote>
+<code>p(x,y) == q(x',y')</code>
+</blockquote>
+for every <code>x</code> and <code>y</code> of type <code>T</code> and <code>x'</code> and
+<code>y'</code> being restored copies of <code>x</code> and <code>y</code>,
+respectively.
+</p>
+
+Operation: saving of a <code>multi_index_container</code> <code>m</code> to an
+output archive (XML archive) <code>ar</code>.
+
+<blockquote>
+<b>Requires:</b> <code>Value</code> is serializable (XML-serializable). Additionally,
+each of the indices of <code>m</code> can impose another requirements.<br>
+<b>Exception safety:</b> Strong with respect to <code>m</code>. If an exception
+is thrown, <code>ar</code> may be left in an inconsistent state.
