A [string](https://learn.microsoft.com/dotnet/api/system.string) which represents the value of the data type description node.

**Remarks**

The time consumed by the first call of the property depends on the availability of the server, because of the [Value](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcattribute/#value) attribute is requested on-demand and is cached for subsequent calls. This means, that further requests to this property will take use of already retrieved attribute information and will not demand additional network resources.
