+status=optional
+notes=The trigger crash dump operation is a mechanism for triggering
+  a crash dump in an instance by injecting an NMI (Non-maskable Interrupt)
+  into the instance. It provides a means to dump the production memory image
+  as a dump file which is useful for users. Therefore this operation is
+  considered optional to support.
