To access the DITA Preferences page, open the Preferences dialog box (Options > Preferences) and go to DITA. This preferences page includes the following sections and options:

DITA Open Toolkit section

This section allows you to specify the default directory of the DITA Open Toolkit distribution (bundled with the Oxygen XML Developer installation) to be used for validating and publishing DITA content. You can select from the following:

Built-in DITA-OT 3.x
Oxygen XML Developer comes bundled with DITA-OT 3.4. By default, all defined DITA transformation/validation scenarios will run with this version. This also provides access to DITA 1.3 features (including document templates). The default DITA-OT 3.4 directory is: [OXYGEN_INSTALL_DIR]/frameworks/dita/DITA-OT3.x.
Custom

Allows you to specify a custom directory for your DITA-OT distribution.

Location
You can either provide a new file path for the specific DITA-OT that you want to use or select a previously used one from the drop-down list. You can specify the path by using the text field, the Insert Editor Variables button, or the Browse button.
Important: Using a custom DITA Open Toolkit may disable certain features in the application. Examples of features that may not work properly:
  • If the custom DITA-OT is missing certain publishing plugins, default transformation scenarios such as DITA Map WebHelp Responsive or DITA Map PDF - based on HTML5 & CSS may no longer work properly.
  • Validation of Markdown documents using Schematron may not work because it is based on a certain DITA Open Toolkit plugin.
  • The DITA framework (defined in the Preferences > Document Type Associations page) will use the XML catalogs specified in the DITA-OT configured in the Preferences > DITA page to perform the validation of all DITA topic types. If this DITA-OT is different from the one that comes bundled with the Oxygen XML Developer default distribution, you might encounter validation-related issues.
CAUTION: Oxygen XML Developer support engineers cannot offer support and troubleshooting assistance for a custom DITA-OT. If you discover any issues or inconsistent behavior while using a custom DITA-OT, you should revert to the default built-in DITA-OT.
