I assume you are looking for some sort of quality requirements like the 
telephone industry has for their various stratum levels.  I don't think you 
will find it.

Basically, stratum 0 is anything from outside NTP.  The "0" doesn't promise 
any quality.

There is a mechanism within ntpd for the driver to report a quality estimate.
