Also Carroll's notes , the part beginning at "We are now in a position to explain the relationship between diffeomorphisms and coordinate transformations." (I haven't read this part carefully, but I quick glance seems to show it's the same argument as Wald's)
Thanks again! Sounds well explained.

I am still interested in understanding Rovelli's argument.
