Property names must be valid python identifiers #6

When I launch _roslaunch robotis_op_gazebo robotis_op_gazebo_position_control_soccer_field.launch_, I get the following error.

Property names must be valid python identifiers: lb-in-in_kg-m-m XacroException(u'Property names must be valid python identifiers: lb-in-in_kg-m-m',)

It seems that the hyphen('-') makes a trouble in xacro. https://github.com/ros/xacro/blob/lunar-devel/src/xacro/__init__.py#L448 And there are some hyphens in robotis_op_description/urdf/constants.xacro.

My environment is Ubuntu 16.04, ROS Kinetic.

To avoid this error, simply comment-out two lines. Then, I can launch the simulation and control a robot!
