> In page 124: "A value of -1 means that the recursion-depth is not limited 
by traversing this field."
> In page 127: "A recursion-depth of 0 will fetch the whole graph of instanc
es reachable from this field"
> Is there a difference between these two?
> In addition, I think that -1 / 0 as a default might be better than 1 it terms of p
erformance, because tracking such cycles has some overhead, which we might not want 
to pay for most fields in which this feature is not needed (and MaxFetchDepth is suf
fic
ient).
