Remarks

In some applications or embeddings of RadDiagram (e.g. workflows) there are shapes or connections which are generated as part of some layout or organization. In those cases it doesn't make sense to serialize the elements which are automatically generated as part of the application. By setting this property to true the serialization pipeline will omit the element.
