DITA 2.0 preview support DITA 2.0 preview DITA Open Toolkit provides an initial preview of features for the upcoming OASIS DITA 2.0 specification. This preliminary processing support is provided on the basis of the latest DRAFT versions of the DITA 2.0 DTD and RelaxNG grammar files from OASIS (as of March 2020).

DITA documents that reference the draft grammar files can be parsed, and where features overlap with DITA 1.3, those features will work as expected.

Other new or revised features proposed for DITA 2.0 are not yet supported. Additional features will be implemented in future versions of DITA-OT as the specification evolves. For the latest status information on DITA 2.0-related features and fixes, see the in the GitHub issues tracker.
