+/**
+ * Handle display of dependent, i. e. optional fieldsets
+ *
+ * Fieldsets may be defined as dependent on the value of a certain input. In
+ * this case they contain a p element with the CSS class “bureaucracy_depends”.
+ * This p element holds a span with the class “bureaucracy_depends_fname”
+ * and optionally another span with “bureaucracy_depends_fvalue”. They
+ * specify the target input (fname) and the target value for which the fieldset
+ * is to be shown.
+ *
+ * This function adds onchange handlers to the relevant inputs for showing and
+ * heading the respective fieldsets.
+ *
