 OSI currently provides only limited support for data structures that describe measured internal states of traffic participants.
 Actuator intentions are currently not covered by OSI and must be handled using a different data description format.
 
-All fields in an interface are set to `optional`.

 `required` is not used.

 This has been done to allow backward-compatible changes in the field.
 Additionally, this is the default behavior in Protocol Buffer version 3 that no longer has the `required` type.
 Setting all fields to `optional` thus ensures update compatibility.
 However, this does not mean that it is optional to fill the field.
 For the purpose of providing a complete interface, all existing fields should be set, unless not setting a field carries a specific meaning, as indicated in the accompanying comment.
 
-All field numbers equal to or greater than 10000 are available for user-specific extensions via custom fields.
+NOTE: All field numbers equal to or greater than 10000 are available for user-specific extensions via custom fields.
 No future evolution of OSI will therefore use field numbers equal to or greater than 10000.
