The child handling in the parameter elements should be fine for this 
purpose, we currently don't verify types or anything specific.

I think before we add this in we should explore a little further what 
goes into a transformation, and what the final result would look like (a 
response for this request).  Do we want to be strict in which 'typeType' 
values to accept?

I am also unsure about the use of the 'timeType' parameter here.  To be 
consistent we may want to use another 'time' object, but I am open to 
debate on that.
