RFC 3966, "The tel URI for Telephone Numbers", December 2004Source of RFC: iptel (rai)
Errata ID: 702
Status: Held for Document Update
Reported By: Alfred Hoenes
Date Reported: 2004-12-04

Section 12 says:
Fate of "fax" and "modem" URI schemes RFC 3966 re-defines the "tel" URI scheme and obsoletes RFC 2806 which defined (and registered) three URI schemes: "tel", "fax", and "modem". Section 12 of RFC 3966 (on page 15) merely states: "references to ... fax and modem URIs ... have been removed." There are *no* IANA considerations included in RFC 3966 regarding the latter URIs. Hence it is not clear whether these URIs are to be regarded as informally "deprecated" or "de-registered" by this RFC, and therefore should be marked accordingly in the IANA 'URI Schemes' reqistry. If however, by existing policy, URI schemes cannot be "deprecated" or "de-registered", the RFC 3966 meta-information should be changed to say "Updates: 2806" instead of "Obsoletes: 2806", and another errata note should be filed to change the RFC 3966 heading accordingly, to avoid the situation of having no more 'valid' documentation for two registered URI schemes.
It should say:
The fate of the "fax" and "modem" URI schemes should be made clear,
formally, and in an appropriate way.
Requires discussion in the IPTEL working group, where I suggest you
take this discussion. I have my personal opinions as to the deployment
and deployability of the 'fax' URI scheme, but that's not particularly
relevant. I suspect a separate document that performs the appropriate
designation (e.g., historical) would be called for, rather than changing
