This is what "SEM-people" call the indirect effect of x1 through x2 on
y. You can get that by estimating your model in Stata with -sem- and
than use -estat teffects- to see the decomposition of the total effect
of x1 into a direct and indirect effect. See -help sem- and -help
estat teffects-.

Hope this helps,
