"Racial advantages are either automatic or purchased. Automatic advantages are possessed by every member of the race and your character begins with those advantages at no cost. Purchased advantages must be bought like a skill. These skills can be purchased every odd level. Each race also has a unique, shared disadvantage."

"Chosen Enemy (Automatic): Upon character creation, the Wild Elf must choose one Chosen Enemy racial group against which they are additionally effective. The reasons for this vary from Wild Elf to Wild Elf. Some Wild Elves despise a race that at some point has done great harm to them, their family or the natural balance of the forest. Others have learned to hunt their Chosen Enemy to support their tribe, with no particular emotional investment. A player can choose as their Chosen Enemy racial group one of the following: Angels/Demons, Animals, Bestial, Brood, Constructs, Draconic, Dwarves, Elementals, Elves, Fae, Goblinoids, Humanoids, Plants, Spirit, Undead (excluding vampires), Vermin (spiders, ants, etc.) The Chosen Enemy ability will grant the Wild Elf a +1 damage bonus on any melee or ranged weapon while fighting against their Chosen Enemy. This bonus will increase +1 for every 3 levels the Wild Elf gains. +1 at first level, +2 at fourth level, +3 at 7th level and so on. This damage bonus will not carry over to any other racial group, but does apply to any race within the racial group. For example, a Wild Elf with Chosen Enemy: Elves does bonus damage against Dark Elves, High Elves,Wild Elves, etc. Chosen Enemy cannot be changed after character creation."

"Sap is a Surprise Attack which allows a character to knock out a victim by touching them in the Upper Back (25) armour location with a coreless, red hand to hand boffer weapon. This represents a hard strike with a blunt object to the back of the head. The attacker must be holding the weapon they are Sapping with, but does not physically strike the target with it. Sap must be done from behind the target. Upon a successful strike, the victim loses 1 Body point and is knocked unconscious for 10 minutes. The base damage for Sap is 1, but may be increased by standards means other than weapon specialisations, such as Strength and magic. The call for Sap is “ Sap”, eg: “2 Silver Sap”. A Sapped character will awaken only once the Sap Body point damage is healed or 10 minutes have passed. A given target can only be Sapped once per minute. No skills or abilities may be used in conjunction with Sap. A Sap will be stopped by a helmet of any kind, standard spell defenses, or a threshold above the Sap’s damage. A helmet will not stop a Sap if all the target’s armour is breached. Sap does not affect Undead or creatures with alien physiology. This skill is usable once per day per purchase."

Question

Is the Wild Elf racial 'Chosen Enemy' one of the ways to increase the damage of a Sap? From the wording about automatic vs purchasable racials, it seems clear that purchasable racial abilities are skills, but it's not clear to me in the automatic advantages are, for the purposes of things like this, or in general.
