What are racial subtypes in your world?
In mine, racial subtypes are culture; that is, the shared features are part of the creature's innate physiology, whereas the non-shared features are imparted by cultural experience.
For example, in my world, all dwarves have innate instincts about stone (Stone-cutting), and their physiology makes them hardier and poison resistant(Constitution bonus, Dwarves Resilience), as well as slower and able to see in the dark. Mountain Dwarves live under a stricter (and more racially homogenous) society, which includes mandatory military service(Strength bonus and armor proficiency); whereas Hill Dwarves are healthier due and their expanded experiences(with others, in less controlled and organized society, looking up) makes them wiser(Wisdom bonus).
As a more direct example, a High Elf's Fey Heritiage, Keen Senses and Trancing would be innate, but it would learn how to use "Elf Weapons", use a single cantrip, and and this would.
In your case, I would say that the character is an Elf, and based on what happens to it, it can gain any of the Elven subtypes. (Yes it is possible for a Wood Elf and a Dark Elf to have a kid who goes away to college and comes back more Intelligent and High :P)
