+        - 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.
