To change the value of a configuration setting partway through a DITA file, you assign a new value to a configuration variable. You can insert a PI marker that contains the assignment or (for some settings) define a DITA2Go macro that includes the assignment. Both methods allow you to shift configuration values back and forth within the same DITA file.
