To answer the original question of:
"what kind of restriction if the tail wind exceed 10kts during autolanding?
The restrictions are likely runway condition (dry, not wet) and a total wind or gust limitation. You could have a 15 kts tailwind component approved, but only if TOTAL report wind is less than XX kts, or gusts 5 kts or less, etc. This is to try and avoid you actually having more than the 15 kts that you calculated at the time of landing.
Only place where I know it is routinely used is in Japan, to avoid circling.
