+                The Juju API uses strictly typed data-types, so we must make
+                sure the parameters from the VNFD match the appropriate type.
+
+                The honus will still be on the operator, to make sure the
+                data-type in the VNFD matches the one in the charm. N2VC will
+                raise N2VCPrimitiveExecutionFailed when there is a mismatch.
+
+                There are three data types supported by the YANG model:
+                # - STRING
+                # - INTEGER
+                # - BOOLEAN

+                Each parameter will look like this:
+                {
+                    'seq': '3',
+                    'name': 'testint',
