Re: Types of CDP in RFC2459

["Housley, Russ" <rhousley@xxxxxxxxxxxxxxx>]

RFC 2459 includes the syntax:

   CRLDistPointsSyntax ::= SEQUENCE SIZE (1..MAX) OF DistributionPoint

   DistributionPoint ::= SEQUENCE {
        distributionPoint       [0]     DistributionPointName OPTIONAL,
        reasons                 [1]     ReasonFlags OPTIONAL,
        cRLIssuer               [2]     GeneralNames OPTIONAL }

      GeneralNames ::= SEQUENCE SIZE (1..MAX) OF GeneralName

      GeneralName ::= CHOICE {
           otherName                       [0]     OtherName,
           rfc822Name                      [1]     IA5String,
           dNSName                         [2]     IA5String,
           x400Address                     [3]     ORAddress,
           directoryName                   [4]     Name,
           ediPartyName                    [5]     EDIPartyName,
           uniformResourceIdentifier       [6]     IA5String,
           iPAddress                       [7]     OCTET STRING,
           registeredID                    [8]     OBJECT IDENTIFIER}

Each of these name forms can be used.  For example, directoryName points to 
an entry in an X.500 directory.

In the PKIX WG we did not make any statements about name forms associated 
with non-Internet protocols.  The standards groups associated with those 
protocols should construct such profiles, if approriate.
