+<p>When writing a derived class, you must use the derived class <codeph>ConstructL()</codeph> to
+call the correct base class <codeph>ConstructL()</codeph>. </p>
+<p>Call the base class <codeph>ConstructL()</codeph> before the derived-class
+specific construction starts. This mirrors the action of C++ constructors.</p>
