+      <p>
+        An alternative form of the <code>&lt;action&gt;</code> element
+        allows you to specify several issues and/or several due-to
+        elements:
+      </p>
+
+<source><![CDATA[
+      <action dev="vmassol" type="fix">
+        <description>Corrected bug blah blah.</description>
+        <fixes issue="JIRA-XXX"/>
+        <fixes issue="JIRA-YYY"/>
+        .
+        .
+        .
+        <dueto name="John Doe" email="john@doe.com"/>
+        <dueto name="Jane Doe"/>
+        .
+        .
+      </action>
+]]></source>
+
+      <p>
+        The <code>&lt;fixes&gt;</code> element takes one required <code>issue</code>
+        attribute, the <code>&lt;dueto&gt;</code> element requires only the <code>name</code>
+        attribute, the <code>email</code> is optional. Note that the <code>&lt;description&gt;</code>,
+        <code>&lt;fixes&gt;</code> and <code>&lt;dueto&gt;</code> elements take precedence over
+        any equivalent attributes defined in the <code>&lt;action&gt;</code> element.
+      </p>
