G-code question

Hi all !
I'm writing a utility to translate my drawings top G-code. I would like an
expert opinion:
is this G-code sintax acceptable ?

G1 X0.0 Y0.0 X2.0 Y2.0 X3.0 Y4.3 W0.0 U0.0 W1.0 U1.0

In this case, I hope that the controller will move the XY point from 0,0 to
2,2 an then to the final destination at 3,4.3 while in the same time the
point WU will move from 0,0 to 1.1. The controller will change the speed to
make the points be reached in the same time.


What I mean is: is acceptable to give multiple X Y and W U movement in the
same block ?.
And if yes the number of XY move must match the WU one ?

If the answer will be yes my program is already done !!!

Thanks for your input !
