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.
