-                <para>Entries in the journal resemble an environment
-                block in their syntax but with fields that can
-                include binary data. Primarily, fields are formatted
-                UTF-8 text strings, and binary formatting is used only
-                where formatting as UTF-8 text strings makes little
-                sense. New fields may freely be defined by
-                applications, but a few fields have special
-                meaning. All fields with special meanings are
-                optional. In some cases, fields may appear more than
-                once per entry.</para>

+    <title>Description</title>
+
+    <para>Entries in the journal resemble an environment block in
+    their syntax but with fields that can include binary data.
+    Primarily, fields are formatted UTF-8 text strings, and binary
+    formatting is used only where formatting as UTF-8 text strings
+    makes little sense. New fields may freely be defined by
+    applications, but a few fields have special meaning. All fields
+    with special meanings are optional. In some cases, fields may
+    appear more than once per entry.</para>
