KDL 2.0 compliance #15
Description
KDL 2.0.0-draft.3 is now generally available (kdl-org/kdl#286), and with it, we've decided to encourage existing implementations to start working towards 2.0 support and send feedback and suggestions for anything you might run into, so I'm making this tracking issue. :)
P.S. We might want to just wait until #12 happens and that grammar is updated for 2.0.
