Currently they just escape to <translate> etc. If the were elements we could potentially support them, but for the time being mark them as AlienMeta so they are at least out of sight.
Very similar to bug 48891.
Once we resolve the discussion in 48891, we can reassign it to Parsoid for any necessary action on our part. *** This bug has been marked as a duplicate of bug 48891 ***
