readOnly property

bool readOnly
final

The value of these keywords MUST be a boolean. When multiple occurrences
of these keywords are applicable to a single sub-instance, the resulting
behavior SHOULD be as for a true value if any occurrence specifies a true
value, and SHOULD be as for a false value otherwise.

If "readOnly" has a value of boolean true, it indicates that the value of
the instance is managed exclusively by the owning authority, and attempts
by an application to modify the value of this property are expected to be
ignored or rejected by that owning authority.

Implementation

final bool readOnly;
