If by Syntax you mean attributes, most NAS will work correctly with

Acct-Session-ID		# Identifies the session to make sure a retransmit doesn't disconnect the use again.
NAS-IP-Address		# Identifies the NAS to make sure the request wasn't routed incorrectly.
User-Name		# Identifies the User, to make it really unlikely that an old session id will accidentally disconnect a user

At least that's the rationale I assume most NAS vendors have behind choosing
those attributes. Really it's quite arbitrary, and you should consult your
vendor's documentation to be sure. 

You can thank the authors of RFC 3576 for the ambiguity.
