[...] Use of the +xml convention implies that such metadata needs to be overridden (e.g. by implying further metadata) in order to process the content any further than the first character. You will find further information in the TAG finding that supports my claim, for example, the HTML sniffing in section 2.1 is not much different from gzip compression sniffing. You will also find that the AWWW document goes even further and constraints "Agents MUST NOT ignore message metadata without the consent of the user" and includes the principle "Agents that recover from error by making a choice without the user's consent are not acting on the user's behalf". The proposed registration does not discuss user consent in any way and is thus inconsistent with the requirement in the TAG finding, and actually with the "Architecture of the World Wide Web", too. If the registration is changed to require user consent to this operation it might be more consistent with these TAG findings; I would not accept such a resolution though. I very much disagree that the TAG supports silent error recovery. If you think my interpretation of these TAG publications is not what the TAG really intended, please request that the TAG clarifies their materials so we can discuss this on more solid grounds. -- Björn Höhrmann · mailto:bjoern@hoehrmann.de · http://bjoern.hoehrmann.de Weinh.
