+  <title>Sanity checks</title>
+  <para>
+    Amtk has several functions to do various sanity checks. They normally don't
+    impact too much the performances, so it is recommended to always run them,
+    although they could be disabled on production. The functions:

+        Another sanity check, but which cannot be disabled: the
+        <link linkend="AmtkActionInfoCentralStore">AmtkActionInfoCentralStore</link>
+        checks that each <link linkend="AmtkActionInfo">AmtkActionInfo</link>
+        has a unique action name. Which means that
+        <link linkend="AmtkActionInfo">AmtkActionInfo</link>'s provided by a
+        library must be namespaced.
