This document defines the syntax and semantics for the Clearance 
   attribute and the Authority Clearance Constraints extension in X.509 
   certificates.  The Clearance attribute is used to indicate the 
   clearance held by the subject.  The Clearance attribute may appear in 
   the subject directory attributes extension of a public key 
   certificate or in the attributes field of an attribute certificate.  
   The Authority Clearance Constraints certificate extension values in a 
   Trust Anchor (TA), Certificate Authority (CA) public key 
   certificates, and an Attribute Authority (AA) public key certificate 
   in a public key certification path constrain the effective Clearance 
   of the subject.
