We also need to know the "syntax" of these attributes. (I use quotes
around "syntax" because my understanding of the term as it's used in
this context is that it's really the set of legal values, i.e. the
type, and not a syntax in the traditional sense.)

Subject: Re: Encoding e-mail addresses as DN's: draft
domainComponent ::= {ccitt 9 2342 19200300 100 1 25}
rfc822Mailbox ::= {ccitt 9 2342 19200300 100 1 3}
The representation of each of these attributes is IA5String. [Can
someone help me here? I've forgotten the numbers for "ccitt".]
CCITT = 0. A commented notation for your numbers would be:
domainComponent OBJECT IDENTIFIER ::=
{ccitt(0) network-operator(9) pss(2342)
ucl(192003000) 100 1 25}
rfc822Mailbox OBJECT IDENTIFIER ::=
{ccitt(0) network-operator(9) pss(2342)
ucl(192003000) 100 1 3}
The binary encoding for these values is 10 byte long, due to the particular
OID choice:
dc = '0992268993F22C640119'H
rm = '0992268993F22C640103'H
I am not very happy with basing an Internet usage on an UCL owned X.25 number.
Apart from being bulky, this is also unstable - suppose that UCL get
renumbered by PSS? I suggest that you denote these assignments as provisional,
and ask IANA for a proper number.
