Re: [ros-users] XmlRpcValue Array in launch file

Hi Bill,

The <rosparam> is what you're looking for (the <param> tag is a
vestigial bit from roslaunch predating rosparam). The rosparam tag is
compatible with the YAML representation and is much more flexible with
value representations, as other people have noted.
