And now:
{{{

| Type notebook() for the GUI, and license() for information. |
----------------------------------------------------------------------
sage: R.<a,b> = NumberField(x^2-3,'g').extension(x^2-7,'h')[]
sage: h = R.base_ring().gen()
sage: S.<y> = R.fraction_field()[]
sage: xgcd(y^2, a*h*y+b)
(b^2/(7*a^2), 1, ((-1)/(h*a))*y + b/(7*a^2))
}}}
This actually looks correct to me. I'm cc-ing the original poster so he
can comment on it.
