I can’t find a good explanation regarding tags that have two different formats, for example:
<always_on> and <alwaysOn>, <update_rate> and <updateRate> and so on.
The one thing I have noticed is the all lowercase one’s precede the actual plugin:
<plugin name="kinect_controller" filename="libgazebo_ros_openni_kinect.so">
and the one’s with caps follow the plugin. What is the reason for the two and why is one placed before and the other place after the plugin ?
