link.to.self.for.mediaobject
     — Include a element to image objects itself to go to a full-size, freely-zoomable version
  
In some cases, it can be very helpful to be able to click on an embedded figure
      or informalfigure to get a full-size, freely-zoomable version of an image, for
      instance when targeting readers on smartphones. This is implemented for images only, but not
      for audio or video objects. 
If non-zero, the image will be wrapped in an a element, using the href 
      attribute pointing to the image itself: 
<a href="source/image"> <!-- the image object --> </a>
 If the value of link.to.self.for.mediaobject.xml is zero
      (default), then no a container is added.
