+    In clause 4.3.2 of ETSI GS NFV-SOL 003 v2.4.1, an attribute-based filtering
+    mechanism is defined. This mechanism is currently not included in the
+    corresponding OpenAPI design for this GS version. Changes to the
+    attribute-based filtering mechanism are being considered in v2.5.1 of this
+    GS for inclusion in the corresponding future ETSI NFV OpenAPI design.
