Your validator is very useful. Thanks for the link.

About my feedback, I have found some problems about SSA service. The 
biggest one, which one is very difficult to check, is when the size 
parameter of your SSA request is important (~10 deg). Sometimes the 
result is an image indicating an error and not a VOTable output. I 
imagine that my request spent the timeout value specified by http server 
and that image was a status code personalized.

People told me that they will implement the error response properly but 
that 10 deg is very large. With apparition of large CCD like MEGACAM 
(FOV : 1deg x 1deg)  and the wide field survey (9 deg x 8deg), people 
may want both image and spectrum data for this survey. So, a size of 10 
deg is not impossible! This kind of error depends also on number of 
request received by minute on the service. I imagine, for the moment, 
the number of requests are not so important to SSA service.

It seems difficult to check this point unless you send some very 
important queries on the service. But I don't think people be very happy 
you do it ;-)

Cheers,
J-Christophe
