can't quote as its a small write up and mostly video:
BBC News - Pakistan allows transsexuals to have own gender category

It will be added as a third gender option on some official documents, including the national ID there (supposedly). Just a note, it was forced by the courts (not willingly by the government from what I'm reading).

Personally I don't see an issue with it, I'm assuming it is mainly for pre-ops (as would think a post-op would pick female or male depending on if they were mtf or ftm).
