How do you create a Windows 7 sysprep answer file that will not prompt to create an account?

I am building a Windows 7 master image to deploy out to approximately 200 computers in my organization. I've configured sysprep to the point that it requires no user interaction except the creation of a new administrator account. How to do configure the sysprep.xml to skip this prompt?
