I just tried this (capturing the id that I was interested in in a closure 
instead of putting it in shr-target-id), but shr-descend only works with 
globally defined functions; is there a reason for that? It's due to the 
following bit: 

        (if (fboundp function)
            (funcall function dom)
          (shr-generic dom))
