Hi again,

Now the SQL MA (trunk) supports point 1) and 2) in the request. I'm 
going to add support for 3) but I'm waiting for your acceptance of using 
nmtm:time element in time parameters. 1) and 2) keeps backward 
compatibility, 3) probably not (I don't know the visualization 
application used in JRA4 but it may not know how to interpret 3)).

please, don't forget about this topic in Brasil (I think it is important 
also for other services)
