i dont think there is a de facto standard ... but i recall some people a
while back saying responses should not exceed about 1MB in size because
of limitations of popular XML processing tools
if your responses are about that size and the RE does not accept them,
let me know and ill increase the limits ...
ps. personally, i think 500 records is fine
