We just released version 2.0 of the Oxygen XML "DITA References"
add-on which now allows you to see for an opened DITA topic both
Outgoing and Incoming references. The incoming references mode is
available only for Oxygen XML Editor version 23.
The add-on can be installed from our regular add-on update site:
I hope you will find this free add-on useful for your work and
any feedback is as usual welcomed.
