+<h2 id="non-standard-attributes">Non-standard C++11 Attributes</h2>
+<!-- ======================================================================= -->
+
+<p>Clang supports one non-standard C++11 attribute. It resides in the
+<tt>clang</tt> attribute namespace.</p>
+
+<!-- ======================================================================= -->
+<h3 id="clang__fallthrough">The <tt>clang::fallthrough</tt> attribute</h3>
+<!-- ======================================================================= -->
+
+<p>The <tt>clang::fallthrough</tt> attribute is used along with the
+<tt>-Wimplicit-fallthrough</tt> argument to annotate intentional fall-through
+between switch labels. It can only be applied to a null statement placed at a
+point of execution between any statement and the next switch label. It is common
+to mark these places with a specific comment, but this attribute is meant to
+replace comments with a more strict annotation, which can be checked by the
+compiler. This attribute doesn't change semantics of the code and can be used
+wherever an intended fall-through occurs. It is designed to mimic
+control-flow statements like <tt>break;</tt>, so it can be placed in most places
+where <tt>break;</tt> can, but only if there are no statements on the execution
+path between it and the next switch label.</p>
+<p>Here is an example:</p>
+<pre>
+// compile with -Wimplicit-fallthrough
+switch (n) {
+case 33:
+  f();
+case 44:  // warning: unannotated fall-through
+  g();
+  <b>[[clang::fallthrough]];</b>
+case 55:  // no warning
+  if (x) {
+    h();
+    break;
+  }
+  else {
+    i();
+    <b>[[clang::fallthrough]];</b>
+  }
+case 66:  // no warning
+  p();
+  <b>[[clang::fallthrough]];</b>  // warning: fallthrough annotation does not directly precede case label
+  q();
+case 77:  // warning: unannotated fall-through
+  r();
+}
+</pre>
