Notation
A read only structural feature is shown using {readOnly} as part of the notation for the structural feature. A modifiable
structural feature is shown using {unrestricted} as part of the notation for the structural feature. This annotation may be
suppressed, in which case it is not possible to determine its value from the diagram.
Presentation Option
It is possible to only allow suppression of this annotation when isReadOnly=false. In this case it is possible to assume this
value in all cases where {readOnly} is not shown.
