 Sometimes a base attribute is needed that applies to all layers. Adding
 this to an existing layer causes problems with duplicate attributes not
 then being recognised. Currently my solution to this is to amended my
 local copy of OpenLayers 2.10 to deal with an extra option of
 baseAttribute. This is then applied first whenever the attributes array is
 recreated for display. I have attached the amended attribution.js file and
 have also emailed in my CLA.
