25+ years ago I worked on X.400 mail. The X.400 specs had a recipient
deceased non-delivery notification IIRC
This is what an RFC822 address looks like in a certificate:
rfc822Name IA5String
This is what an X.400 address looks like in a certificate:
ITU-Braindamge ::= SEQUENCE {
built-in-standard-attributes SEQUENCE {
country-name [ APPLICATION 1 ] CHOICE {
x121-dcc-code
NumericString,
iso-3166-alpha2-code PrintableString
},
administration-domain-name
[ APPLICATION 2 ] CHOICE {
numeric
NumericString,
printable
PrintableString
},
network-address [ 0 ] NumericString
OPTIONAL,
terminal-identifier [ 1 ] PrintableString
OPTIONAL,
private-domain-name [ 2 ] CHOICE {
numeric
NumericString,
printable
PrintableString
} OPTIONAL,
organization-name [ 3 ] PrintableString
OPTIONAL,
numeric-use-identifier [ 4 ] NumericString OPTIONAL,
personal-name [ 5 ] SET {
surname [ 0 ]
PrintableString,
given-name [ 1 ]
PrintableString,
initials [ 2 ]
PrintableString,
generation-qualifier [ 3 ] PrintableString
} OPTIONAL,
organizational-unit-name [ 6 ] PrintableString
OPTIONAL,
}
built-in-domain-defined-attributes SEQUENCE OF {

PrintableString SIZE(1..64),

PrintableString SIZE(1..64)
} OPTIONAL
extensionAttributes SET OF
SEQUENCE {
extension-attribute-type [ 0 ] INTEGER,
extension-attribute-value [ 1 ] ANY DEFINED BY
extension-attribute-type
} OPTIONAL
}
Given that, I would hope that X.400 not only includes a recipient deceased
non-delivery notification but also a detailed record of what the cause of
death was, a complete autopsy report, and an address to send flowers to.
Peter.
