      in one recent case, a client decided to handle these UI list
      dependencies by sending all the data in the form and letting local
      scripts to the filtering w/o the need to call back to the server. in
      this case the lists were quite static (product-related filters) and
      relatively small (tens of items in each list, not hundreds). caching
      makes composing and shipping this representation to the clients
      relatively inexpensive (after the first delivery to a client).
