No just that is you took a little initiative to look down a provided
path you might get to your desired answer sooner. Or you might come
across a reference with a large amount of info such as the Stanford

"The mixture is ignited by the "Augmented Spark Igniter", an H2/O2
flame at the center of the injector head."
