While various forms of address are available for people born with parts of both male and female genitalia, the most common and easiest is intersex. The folks here: http://www.isna.org/faq/ have a lot more to say about it, and seeing as how many of them ARE intersex, I'd leave it up to them. While most transgender folks prefer to be referred to as their assumed gender, there are some gender queer folks who prefer other forms of address. I would put it that gender is not so easily defined, which makes it a poor choice for enum.
