-    * \brief This receiver is for signals related to HTML pages.
-    *
-    * The \em link argument to all signals defines a number, which has
-    * been passed before, e.g. by setting dw::core::style::Style::x_link.
-    * When defining this number (e.g in dw::core::style::Style::x_link),
-    * and when receiving the signal, the caller must interpret these numbers
-    * in a consistent way. In the HTML link block, this number is an index
-    * to an array of URLs.
-    *
-    * \em link = -1 represents an undefined link.
-    *
-    * The \em img argument to all signals defines a number which has
-    * been passed before, e.g. by setting dw::core::style::Style::x_img.
-    * When defining this number (e.g in dw::core::style::Style::x_img),
-    * and when receiving the signal, the caller must interpret these numbers
-    * in a consistent way. In the HTML link block, this number is an index
-    * to an array of structures containing image information.
-    *
-    * \em img = -1 represents an undefined image.
-    *
-    * \em x and \em y define the coordinates within the link area. They are
-    * only used for server-side image maps, see dw::Image.
