+        it might be useful to display different entries in a different color
+        for example. To achieve this, a CSS style sheet can be attached to an
+        entry based on the value of an attribute. If you have an attribute
+        called <code><b>importnace</b></code> and you want to highlight
+        all entries where <code><b>importnace</b></code> is <code><b>severe</b></code>
+        for example, you can specify following style:
+        <pre>
+Style importance severe = background-color:red
+        </pre>
+        For possible formattings, please refer to some CSS documentation. You can
+        change the colors, font styles and sizes.
