			Appendix C. Applicability examples
			As an examample here below is the way and OpenROADM compliant
			equipment could be managed using the Yang models described in thei
			draft.
			In OpenROADM MSA there is a limited number of DWDM interfaces
			supported. Basically only the 100G Staircase FEC and 400G oFEC are
			supported and these two kind of interfaces can be easily summarized
			with the "mode-id" and the "application-identifier" strings.
			the models below are enough to identify the interface and few working
			parameters:
			module: ietf-ext-xponder-wdm-if

			+--rw if-current-mode
