Empty options should be acceptable, e.g. for procedurally generated documents which might or might not inject options into the node, and in any case PMLC should at the most produce a warning but still convert the rest of the document (if valid).

Yes, PMLC must not crash in case of an empty options node. Instead, a warning should be emitted, and execution should continue.

Fixed in version 4.0.0.
