title: OpenLayer static Attribution on the bottom-left of the map
body: <p>I use OpenLayer with the possibility to switch from two different base layers.
  So, I have different Attribution for each layer (as links) on the bottom-right of the map.</p>
  
  <p>Is it possible to add one more Attribution (a link) on the bottom-left of the map?
  I need to have this Attribution shared between all layers (I don't need to change it when I switch layer) </p>
