OpenGL SC and OpenGL ES

I have read in an IEEE paper that OpenGL SC 1.0.1 is an API that is consistent with older OpenGL APIs, but provides a Profile that is suitable for safety-critical applications. OpenGL ES 2.0 is an API that is not compatible with other OpenGL APIs; What do they mean by saying “but provides a Profile that is suitable for safety-critical applications”??? how are OpenGL SC implementation different from that of OpenGL ES implementation.
