Customizing the DITA DTD
You can associate an instance of the DITA-OT with your Stationery design project to apply and track DITA specialization through the Stationery.
To customize the DITA DTD and apply the DITA specialization
In Windows Explorer, open your Stationery design project folder. For more information about override files and locations, see “Understanding Stationery, Projects, and Overrides” on page 327.
Create the Formats\Helpers\dita-ot-1.4 folder in your projectname folder, where projectname is the name of your Stationery design project.
Copy the contents of the following folder to the override folder you created within your project folder:
Program Files\WebWorks\ePublisher Pro\Helpers\dita-ot-1.4
Open the dita-ot-1.4 folder you copied to your project override folder and apply the DTD changes you need for your DITA specialization.
Save and close the modified files.
Regenerate your project to review the changes.
