...and vastly simplify the currently overly complex XML representation. 
I'm willing to sacrifice flexibility so we get something that is easily 
implement-able out the other end. However I'm not asking other people 
to do so, all I'm asking is that something as heavyweight as STC isn't 
the mandatory implementation, and there is a lighter weight alternative 
and the two are interchangeable inside a VOEvent message.

Good.
