Anees, The preconditions requirement in early session is same as the preconditions specified for a regular session. So if a UAC initiates an early session and specifies certain preconditions, then the early session will start only if those preconditions are met and not otherwise.
The early session (or a regular session) requestor adds a precondition requirement when there is a need for certain requirements like Security, QoS, etc are mandatory to be met for establishing the session.

RFC just mentions and provides a reference to RFC 3312 but does not provide any details. I am interested to know if anyone has implemented preconditions for early-sessions. Specifically are there are any servers or endpoints that expect preconditions for early-session? How do you as an early-session requestor "Require" preconditions?
