### 26.8 Overriding DocBook settings with PI markers

You might need to insert PI markers in your document to override configuration settings for particular DocBook elements. DITA2Go provides predefined PI marker types for this purpose, listed in Table 26-1. Most of these PI marker types are intended to provide ways to cope with unusual situations.
