True. The difference is when all you need is a flat configuration scheme
as opposed to a hierarchical one.
Parameters is much like Properties with the exception of type safety built
in. It is a flat configuration scheme--easily derived from a heirarchical
one.
Configuration is for when your Configuration elements need to be expressed
in a more rich manner. It allows you to group sub configurations together
very easily.
As far as the overall weight of the objects, the Parameters object is lighter
than the Configuration object.
