     1560Standard: [https://heycam.github.io/webidl/#Unforgeable The spec of Unforgeable]
     1561
     1562Summary: Indicates that the attribute or operation will be reflected as an ECMAScript property in a way that means its behavior cannot be modified and that performing a property lookup on the object will always result in the attribute’s property value being returned. In particular, the property will be non-configurable and will exist as an own property on the object itself rather than on its prototype.
     1563
     1564Usage: [Unforgeable] can be specified on interfaces, on non-static attributes and on non-static operations. The IDL looks like:
     1565{{{
     1566    [Unforgeable]
     1567    interface XXX {
     1568        readonly attribute unsigned long length;
     1569        DOMString getString(DOMString key);
     1570    };
     1571
     1572    interface YYY {
     1573        [Unforgeable] readonly attribute unsigned long length;
     1574        [Unforgeable] DOMString getString(DOMString key);
     1575    };
     1576}}}
