+/*! \page dbusxml DBus XML output format
+
+\addindex dbusxml
+
+<p>Doxygen can generate documentation for DBus XML files.  This way
+DBus interfaces can be annotated with doxygen style comments, and
+without writing custom XML parsers.  Doxygen extracts its text from
+all XML comments starting with '*' or '!'.  An additional '<' can be
+used to assign the documentation string to the previous entity instead
+of the one following the comment.
+
+Note that before the parsing of DBus XML file works one has to
+assign the .xml extension to the DBus XML parser using the
+following configuration option:
+
+\verbatim
+EXTENSION_MAPPING = xml=dbusxml
+\endverbatim
+
+\section dbusxml_supported Supported XML elements and attributes
+
+<p>The following DBus XML elemets can be annotated:
+
+<ul>
+<li><b>interface</b>
+
+<li><b>method</b> or <b>signal</b>
+
+<li><b>arg</b>
+
+<li><b>property</b>
+
+</ul>
+
+Additional elements are supported. These are available once
+the xmlns "http://psiamp.org/dtd/doxygen_dbusxml.dtd" is
+available.
+
+<ul>
+<li><b>namespace</b>: This can be used to group other more of the
+additional elemets.  This element requires a <b>name</b> attribute.
+
+<li><b>enum</b> is used to define enums.  <b>value</b> element is
+    then used to define the individual values in the enum.  This element
+    requires the <b>name</b> and <b>type</b> attributes.  A
+    optional <b>named-type</b> attribute is allowed, referrencing typed
+    previously defined by one of the additional elements.  A enum name
+    can be used anywhere a type is required using the <b>named-type</b>
+    attribute.
+
+<li><b>flagset</b> is used to define sets of flags. Required and
+    optional attributes are identical to the ones used by <b>enum</b>.
+    While <b>enum</b>s assume the values to be consecutive, while
+    a <b>flagset</b> is values suitable for flags.  A flagset name
+    can be used anywhere a type is required using the <b>named-type</b>
+    attribute.
+
+<li><b>struct</b> is used to define structures. A <b>name</b>
+    attribute is required.
+
+<li><b>member</b> is used to define members of <b>structs</b>.  It
+    is valid inside <b>struct</b> elements. This
+    element requires <b>name</b> and <b>type</b> attributes.  In
+    addition to (or even instead of) the <b>type</b> attribute a
+    <b>named-type</b> attribute may be used to reference types defined
+    by <b>enum</b>, <b>flagset</b> or <b>struct</b>.
