The Pan/Tilt limits element should be present for a PTZ Node that supports an absolute Pan/Tilt. If the element is present it signals the support for configurable Pan/Tilt limits. If limits are enabled, the Pan/Tilt movements shall always stay within the specified range. The Pan/Tilt limits are disabled by setting the limits to –INF or +INF.
