Folks,
It is worth mentioning that there already are mutliple meta-syntax
standards for email local-part strings.
While I have a vague memory of there being more than two, the ones I
know about in detail are:
RFC 3191, Minimal GSTN address format in Internet Mail
RFC 3340,1,3 apex=
RFC 3191 [/] SMS= (example)
RFC 3192 FAX=
RFC 3804 VPIM=, VOICE=, AMIS=
RFC 3801, Voice Profile for Internet Mail - version 2 (VPIMv2)
???
http://cr.yp.to/proto/verp.txt
Where "=" replaces "@" for local-part cascaded addresses.
list-lp"-"subscrib-lp"="subscrib-dom(_at_)list-dom
This means verp overlaps with "tag=" convention.
FWIW:
http://www.openspf.org/SRS
(original paper used "#" instead of "=" and example uses "+")
http://www.libsrs2.org/srs/srs.pdf
SRS0=
SRS1=
Please note that the BATV proposal seems to be compatible with
RFC3191, in terms of having a registered string followed by an equal
sign.
Hmmm.
Perhaps this means we do not need to define a new registry, but
merely add values to the IANA GSTN Service-Selector table?
Why create a new table if we don't have to?
For that matter, why debate about a new syntax if we don't have to?...
Agreed. There is at least some experience in adding meta information
using the "=".
