I ran a test to determine the answer to this question - unfortunately, the function that checks for credentials near the start of the script actually skips checking any credentials where passwords are not defined :p so it's not much use... The only ones you can actually skip in the XML are the install account password (required for auto-login after reboot), the farm account password and the farm passphrase - you will be prompted for each at script run-time.
It turns out that it's FAR easier (and just as secure, IMO) to simply specify the passwords in the XML at install time then change any required passwords immediately after installation. Even the most "locked down" organizations I've worked with will allow this method, since the credentials in the XML become almost immediately void.
