+    <para>In early 2004, Martin Fowler asked the readers of his site: when
+    talking about Inversion of Control: <emphasis>"the question, is what
+    aspect of control are they inverting?"</emphasis>. After talking about the
+    term Inversion of Control Martin suggests renaming the pattern, or at
+    least giving it a more self-explanatory name, and starts to use the term
+    <emphasis>Dependency Injection</emphasis>. His <ulink
+    url="http://martinfowler.com/articles/injection.html">article</ulink>
+    continues to explain some of the ideas behind this important software
+    engineering principle.</para>
