+ "prop1": "value of prop1"
+}

+
+in Format "Value".
+
+Since Capability and Operation are not part of Value-Only serialization they are omitted. 
+Also a List containing elements that are omitted is omitted. This is even the case if the SubmodelElementList is mandatory.
+

+Note: Similar handling is required in case there are access rules disallowing access to specific submodel elements:
+The protected elements shall not be serialized.

 ==== Examples Value-Only serialization for all submodel element types 
 
 In the following examples for Value-Only serializations for all submodel element types are given.
