+<p>Group transit patterns and give each group a mutual advantage in the Raptor search.</p>
 <p>Use this to separate transit patterns into groups. Each group will be given a group-id. A
 path (multiple legs) will then have a set of group-ids based on the group-id from each leg.
 Hence, two paths with a different set of group-ids will BOTH be optimal unless the cost is
-worse than the relaxation specified in the <code>relaxTransitPriorityGroup</code> parameter. This is
+worse than the relaxation specified in the <code>relaxTransitGroupPriority</code> parameter. This is
 only available in the TransmodelAPI for now.</p>
-<p>Unmatched patterns are put in the BASE priority-group (group id: 0). This group is special.
-If a path only have legs in the base group, then that path dominates other paths, but other
