Hi Ray,

ObsDataLocation is actually also in STC. Since there is no hope of 
getting STC to use elementFormDefault="unqualified" (even though it is 
all in one namespace now), we're going to have change the instructions 
we give out to people on how to parse VOEvents and make things a little 
more complicated.
