It is not defined by any RFC, it is simply a hack that was put in to 
address an issue with LDAPv2.  LDAPv3 implements the RFC defined STARTTLS 
operation (RFC 2830).  Just because it is registered with iana doesn't mean 
it is something that's been truly defined.  As such, it faces the 
possibility of disappearing in the future.
