 ``DeclContext`` manages multiply-defined declaration contexts internally.  The
 function ``DeclContext::getPrimaryContext`` retrieves the "primary" context for
 a given ``DeclContext`` instance, which is the ``DeclContext`` responsible for
-maintaining the lookup table used for the semantics-centric view.  Given the
-primary context, one can follow the chain of ``DeclContext`` nodes that define
-additional declarations via ``DeclContext::getNextContext``.  Note that these
-functions are used internally within the lookup and insertion methods of the
-``DeclContext``, so the vast majority of clients can ignore them.
