     Image handling requires a little extra work from the application, to choose an
-    appropriate image format for the target HTML viewer and to clean up the
-    temporary images
-    later. If you are planning to load the HTML into a standard web browser, you can
+    appropriate image format for the target HTML viewer and to clean up the temporary
+    images later.
+    If you are planning to load the HTML into a standard web browser, you can
     specify the handler flag wxRICHTEXT_HANDLER_SAVE_IMAGES_TO_BASE64 (the default)
     and no extra work is required: the images will be written with the HTML.
 
     However, if you want wxHTML compatibility, you will need to use
-    wxRICHTEXT_HANDLER_SAVE_IMAGES_TO_MEMORY
-    or wxRICHTEXT_HANDLER_SAVE_IMAGES_TO_FILES. In this case, you must either call
-    wxRichTextHTMLHandler::DeleteTemporaryImages before
-    the next load operation, or you must store the image
-    locations and delete them yourself when appropriate. You can call
-    wxRichTextHTMLHandler::GetTemporaryImageLocations to
+    @c wxRICHTEXT_HANDLER_SAVE_IMAGES_TO_MEMORY or
+    @c wxRICHTEXT_HANDLER_SAVE_IMAGES_TO_FILES.
+
+    In this case, you must either call wxRichTextHTMLHandler::DeleteTemporaryImages
+    before the next load operation, or you must store the image locations and
+    delete them yourself when appropriate.
+
+    You can call wxRichTextHTMLHandler::GetTemporaryImageLocations to
     get the array of temporary image names.
 
+
+    @section richtexthtmlhandler_flags Handler flags
+
+    The following flags can be used with this handler, via the handler's SetFlags()
+    function or the buffer or control's SetHandlerFlags() function:
+
+    - wxRICHTEXT_HANDLER_SAVE_IMAGES_TO_MEMORY
+      Images are saved to the memory filesystem: suitable for showing wxHTML windows.
+    - wxRICHTEXT_HANDLER_SAVE_IMAGES_TO_FILES
+      Images are saved to temporary files: suitable for showing in wxHTML windows.
+    - wxRICHTEXT_HANDLER_SAVE_IMAGES_TO_BASE64
+      Images are written with the HTML files in Base 64 format: suitable for showing
+      in web browsers.
+    - wxRICHTEXT_HANDLER_NO_HEADER_FOOTER
+      Don't include header and footer tags (HTML, HEAD, BODY), so that the HTML
+      can be used as part of a larger document.
