The DITA Troubleshooting specialization is now available as a plug-in to the DITA Open Toolkit. The Troubleshooting specialization creates a new topic type that is well-suited for problem-solution information. This topic type is based on the generic DITA topic type, and is based on the OASIS DITA standard. The Troubleshooting specialization should be placed in the \plugins directory of the Open Toolkit. You should run ant -f integrator.xml on the command line from the toolkit root directory after unzipping the package. This will properly "integrate" the package.
