Transgender Passport Change

From Yahoo News:
"New Passport Rules Ease Switch for Transgenders"

I don't think this is a very good law. Just because a man dresses as a woman doesn't make him a woman. If he undergoes surgery and then becomes a woman than I think she should then be allowed to change her gender on her passport or any other document. What happens if the man (who hasn't had the surgery) changes his mind and stops acting as a woman? By having the surgery proves beyond a doubt that they are committed to changing their gender - especially because it is so expensive.
