The IAB would like to make the EBU/ETSI JTC Broadcast aware of the registration
process for URI schemes as defined in Section 7.2 of RFC7595. It was brought to
our attention that ETSI TS 102 818 V3.4.1 (2022-05) uses the URI scheme
“postal”, but we have not found a registration for it in the URI Schemes IANA
registry. RFC7595 describes a registration process, which is "first come first
served" for provisional registrations and based on expert review for permanent
URI schemes. In order to avoid the risk that others might also choose the same
scheme name, the IETF recommends potential registrants to note the scheme name
in the registry as soon as possible. We therefore request you to apply the
registration process as specified in RFC7595. This will ensure nobody else will
be able to officially register the “postal” scheme with conflicting syntax
and/or semantics.

Thanks for your cooperation on this matter!
