Most of these architectural considerations were examined and abandoned 
early in the process (though granted this was without much discussion on 
the list).

The reason it is the way it is:  by separating collections from simples, 
we can precisely define the inputs to a service - a single object, a 
defined number of objects, or an undefined number of objects, as well as 
any combination of these (e.g. a collection of sequences plus a single 
sequence as a service input).  This could not (unambiguously) be defined 
with Phillips suggestion without adding another parameter to the service 
signature... which then becomes six or a half dozen.
