Copy of titan.core#693 ## Summary ASN.1 `SelectionOption` is not supported, i.e. `WITH SUCCESSORS` and `WITH DESCENDANTS`. The IEE1609.2.1 standards are using extensively the statement WITH SUCCESSOR, therefore it would be nice to have it in Titan as well. The issue originates from this forum topic: https://www.eclipse.org/forums/index.php/t/1112635/ /cc @aknappqwt @mmagyari
