SCXML <send> namelistexpr

Most attributes of <send> come in both static and dynamic flavors.  For 
example, event expects a static string, while eventexpr is evaluated at 
runtime.  The current SCXML draft does not list a dynamic version of 
namelist.  Does there exist a way to dynamically construct a namelist for 
<send>?  If not, should we add namelistexpr to the list of possible <send> 
attributes?

Thanks,
Pierre
