The idea is to enable easier replacement of the DTML/SQL method code. 
 Also, you want something that forces a singular parameter binding 
function onto the DA, rather than having the higher level code be more 
versatile (and understand the 5 or so different types of parameter 
binding.)  The DA can then convert to the underlying adapter.
