See the ticket [1] for (one sided) discussion on the decision to use an 
srs object.

Executive summary: IE push slow.

The one drawback of using an object is that you don't have length.  I 
didn't see this as a serious drawback (and instead decided that the 
layer.srs["EPSG:4326"] type test was very useful).  Please write back if 
you have a good use case for an array.
