17.13.2 says "Every successful control has its control name paired with 
its current value as part of the submitted form data set."

So I'd say the value should be sent too, not only x and y, but then 
again, I'm not writing browsers, only apps for them...

http://www.php.net/manual/en/language.variables.external.php tells us: 
"The experienced may note that the actual variable names sent by the 
browser contains a period rather than an underscore, but PHP converts 
the period to an underscore automatically."

So you'll have Submit_x and Submit_y instead of Submit.x and Submit.y
