How can I set the preserveWorldVelocity flag in Gazebo 9 (hopefully through roslaunch and urdf)?

In order to get rid of unwanted behavior in Gazebo 7, I have installed Gazebo 9 in hopes of setting the preserveWorldVelocity flag. (Is "flag" the proper term?) I'm using roslaunch and xacro to start my simulation. In the robot xacro I have

<gazebo>
  <self_collide>1</self_collide>
</gazebo>

but trying something similar with

<preserveWorldVelocity>1</preserveWorldVelocity>

has no effect. Can you tell me how to set this flag so that using PositionJointInterface does not mean velocities are repeatedly cleared?

The solution is to install the latest version of gazebo_ros_pkgs from source (http://gazebosim.org/tutorials?tut=ro...). With that package _preserveWorldVelocity is true.
