Set orientation in a .world file

Hi! Using tum_simulator for indigo I'm trying to create my own world. I can import my meshes and lights using the sdf syntax, but when I try to change orientation of a spot light (pitch in particular), nothing happens in Gazebo (orientation is setted on [0 0 0]). This is my .world file:10 0 10 0 -0 00.8 0.8 0.8 10.2 0.2 0.2 110000.90.010.001-0.5 0.1 -0.912.5 7.9 4.0 0 -0.5 00.8 0.8 0.8 10.2 0.2 0.2 1200.50.010.00110 0 1100 100100501000 0 1100 100000010.001110000 0 -9.80.4 0.4 0.4 10.7 0.7 0.7 111model://museum/meshes/museum.dae10model://museum/meshes/museum.dae000010 0 0 0 -0 01.49016 -3.72367 3.62379 -2.88294e-17 0.273797 1.4042orbit and the light named "spot1" is created into Gazebo with orientation 0 0 0. Can someone help me? Thank you ;)
