XSLfast can be used with various Renderers. The Renderer FOP is delivered with XSLfast but it can also be used with e.g. XEP by RenderX or XSLFormatter by AntennaHouse. Due to the used Renderer, some functions of XSLfast will not work and thus are not available in the application. Nevertheless, this manual describes all functions of XSLfast. So if you notice that there are functions described here which you could not find or use in the application, it is a limitation due to the currently selected Renderer.
