Acrolinx for Oxygen XML Web Author checks your XML and DITA documents. Before you run a check, it's best to switch off track changes. Acrolinx doesn't support track changes, so you might see some unexpected behavior if it's switched on.
Acrolinx for Oxygen XML Web Author supports DITA map checks. When you check a DITA map, the Sidebar doesn't highlight issues in the text or replace issues for you. The cards give you all the information you need to correct your content. You can edit your issues directly and use all the other features of the Sidebar.
Supported DITA references:
DITA reference and DITA map support is available starting with platform version 2019.10, but you'll get the best results with platform version 2020.03 and later.
