+        - The TAPI YANG models included in this TAPI release are a *normative* part of the TAPI SDK.
+        - The YANG specifications have been generated from the corresponding UML model using the [ONF EAGLE UML2YANG mapping tool]
+          <https://github.com/OpenNetworkingFoundation/EagleUmlYang>
+          and further edited manually to comply with the [ONF IISOMI UML2YANG mapping guidelines]
+          <https://wiki.opennetworking.org/display/OIMT/UML+-+YANG+Guidelines>
+        - Status of YANG model artifacts can be determined by referring to the corresponding UML artifacts.
+          As described in the UML models, some artifacts are considered *experimental*, and thus the corresponding YANG artifacts.
+        - The ONF TAPI release process does not guarantee backward compatibility of YANG models across major versions of TAPI releases.
+          The YANG model backward compatibility criteria are outlined in section 11 of <https://tools.ietf.org/html/rfc7950>.
+          YANG models included in this release may not be backward compatible with previous TAPI releases.

+            If an FC exposes protection (having two or more FcPorts that provide alternative identical inputs/outputs), the FC will have one or more associated FcSwitch objects to represent the alternative flow choices visible at the edge of the FC.
+            The FC switch represents and defines a protection switch structure encapsulated in the FC.
+            Essentially performs one of the functions of the Protection Group in a traditional model. It associates to 2 or more FcPorts each playing the role of a Protection Unit.
+            One or more protection, i.e. standby/backup, FcPorts provide protection for one or more working (i.e. regular/main/preferred) FcPorts where either protection or working can feed one or more protected FcPort.
+            The switch may be used in revertive or non-revertive (symmetric) mode. When in revertive mode it may define a waitToRestore time.
+            It may be used in one of several modes including source switch, destination switched, source and destination switched etc (covering cases such as 1+1 and 1:1).
+            It may be locked out (prevented from switching), force switched or manual switched.
+            It will indicate switch state and change of state.
+            The switch can be switched away from all sources such that it becomes open and hence two coordinated switches can both feed the same LTP so long as at least one of the two is switched away from all sources (is 'open').
+            The ability for a Switch to be 'high impedance' allows bidirectional ForwardingConstructs to be overlaid on the same bidirectional LTP where the appropriate control is enabled to prevent signal conflict.
