I agree with Rick that this seems to conflate the encoding (ISOTime) and the 
fact that it is a timestamp. That is, the last dot in the above utype is 
crossing the boundary from data model to format. So this would look better to 
me as:

utype="stc:AstroCoords.Time.TimeInstant" format="iso8601" 

That would be OK for a "generic" timestamp in services with no other data 
model, which still leaves one having to replace that utype with another one 
from a higher level data model,
