=head1 STANDARD EXTENSIONS
The value of B<dirName> should point to a section containing the distinguished
name to use as a set of name value pairs. Multi values AVAs can be formed by
-preceeding the name with a B<+> character.
+prefacing the name with a B<+> character.
otherName can include arbitrary data associated with an OID: the value
should be the OID followed by a semicolon and the content in standard
-ASN1_generate_nconf() format.
+L<ASN1_generate_nconf(3)|ASN1_generate_nconf(3)> format.
Examples:
=head2 CRL distribution points.
-This is a multi-valued extension that supports all the literal options of
-subject alternative name. Of the few software packages that currently interpret
-this extension most only interpret the URI option.
+This is a multi-valued extension whose options can be either in name:value pair
+using the same form as subject alternative name or a single value representing
+a section name containing all the distribution point fields.
-Currently each option will set a new DistributionPoint with the fullName
-field set to the given value.
+For a name:value pair a new DistributionPoint with the fullName field set to
+the given value both the cRLissuer and reasons fields are omitted in this case.
-Other fields like cRLissuer and reasons cannot currently be set or displayed:
-at this time no examples were available that used these fields.
+In the single option case the section indicated contains values for each
+field. In this section:
+
+If the name is "fullname" the value field should contain the full name
+of the distribution point in the same format as subject alternative name.
+
+If the name is "relativename" then the value field should contain a section
+name whose contents represent a DN fragment to be placed in this field.
+
+The name "CRLIssuer" if present should contain a value for this field in
+subject alternative name format.
+
+If the name is "reasons" the value field should consist of a comma
+separated field containing the reasons. Valid reasons are: "keyCompromise",
+"CACompromise", "affiliationChanged", "superseded", "cessationOfOperation",
+"certificateHold", "privilegeWithdrawn" and "AACompromise".

+ reasons=keyCompromise, CACompromise
+
+ [issuer_sect]
+ C=UK
+ O=Organisation
+ CN=Some Name
+
+=head2 Issuing Distribution Point
+
+This extension should only appear in CRLs. It is a multi valued extension
+whose syntax is similar to the "section" pointed to by the CRL distribution
+points extension with a few differences.
+
+The names "reasons" and "CRLissuer" are not recognized.
+
+The name "onlysomereasons" is accepted which sets this field. The value is
+in the same format as the CRL distribution point "reasons" field.
+
+The names "onlyuser", "onlyCA", "onlyAA" and "indirectCRL" are also accepted
+the values should be a boolean value (TRUE or FALSE) to indicate the value of
+the corresponding field.
+
+Example:
+
+ issuingDistributionPoint=critical, @idp_section
+
+ [idp_section]
+
+ fullname=URI:http://myhost.com/myca.crl
+ indirectCRL=TRUE
+ onlysomereasons=keyCompromise, CACompromise
+
+ [issuer_sect]
+ C=UK
+ O=Organisation
+ CN=Some Name
+
+
=head2 Certificate Policies.
This is a I<raw> extension. All the fields of this extension can be set by
nameConstraints=excluded;email:.com
+
+=head2 OCSP No Check
+
+The OCSP No Check extension is a string extension but its value is ignored.
+
+Example:
+
+ noCheck = ignored

=head1 DEPRECATED EXTENSIONS
The following extensions are non standard, Netscape specific and largely
There are two ways to encode arbitrary extensions.
The first way is to use the word ASN1 followed by the extension content
-using the same syntax as ASN1_generate_nconf(). For example:
+using the same syntax as L<ASN1_generate_nconf(3)|ASN1_generate_nconf(3)>.
+For example:
1.2.3.4=critical,ASN1:UTF8String:Some random data
=head1 SEE ALSO
