    @class wxRichTextXMLHandler

    A handler for loading and saving content in an XML format specific
    to wxRichTextBuffer.

    You can either add the handler to the buffer and load and save through
    the buffer or control API, or you can create an instance of the handler
    on the stack and call its functions directly.


    @section richtextxmlhandler_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_INCLUDE_STYLESHEET
      Include the style sheet in loading and saving operations.
