Update the Output Generator
This procedure assumes you have completed all changes to CompanyDitabase.dtd and CompanyMap.dtd in your custom DTD plugin.
Dynamic Release Management (DRM) concerns for upgrading the Output Generator to DITA 1.3
All of the DRM functionality is defined within the com.ixiasoft.dita13.dtd plugin. By installing this plugin in the Output Generator, you automatically take care of any DRM concerns with respect to DITA 1.3. None of the pertinent files should be a part of your custom DTD plugin; therefore, you should not have any DRM-specific changes to make in your custom DTD plugin.
