Oxygen XML Forum

Hi There:
When I use oXygen v24, I don't get an error, but if I use v25.1, I get the following. I want to try to update the "ditaval file", but I don't know where to look for it. If I click on the message, it just takes me to an expanded version of the .ditamap file. Suggestions, please?

Hi Stacey,
Each update of Oxygen usually comes with the latest DITA Open Toolkit publishing engine. This particular message you see is not an error or warning message, it's an information message which can probably be ignored in most cases, and was added in the publishing engine in a recent version of it.
About the ditaval file, usually it's a file with the extension ".ditaval" which is used by your transformation scenario to publish.
If you edit the "Release Notes - 19.x" transformation scenario in Oxygen, it should have a "Filters" tab in which you have probably specified a reference to a filter file.
Regards,
Radu
