Let's say you can show your thumb leftwards, rightwards, or do something else. Is that a voting protocol? No, because whatever you do you would still be within the limits of the protocol, and there is no difference between doing one thing or another as far as the protocol is concerned. Let's say you can show your thumb up, down, or do something else. Is that a voting protocol? Yes, to some degree anyway, since it is normal to assume that people speak to some degree in metaphor, and if you are familiar with ancient Rome you are likely to associate up with life and down with death (and "life" as affirmative or positive and so on). It is unclear to me whether this is meant to be a transient problem or a permanent one (whether this is about how Working Drafts should be orga- nized, or about how the Recommendations should be organized), but by the time the Tracking Preference Expression specification mentions tracking you are firmly in the up/down setting, so there is no "clear boundary" between the specifications. Realistically the Tracking Preference Expression specification will have to indicate that DNT:0 means less tracking than DNT:1 in some form (or was it the other way around? If it just defines syntax you would not know from reading only the specification), so there will not be a clear boundary between the specifications either. So it seems to me that you will have to discuss where the boundaries are supposed to be and how to link across them. (In passing I note that I have used 'dnt-relevant tracking' in the past to refer to whatever "tracking" the WG might end up addressing when it has determined what it wants to address; splitting syntax and semantics as is being proposed seems like a bad idea to me, but a neutral "this is defined elsewhere"-indicating term does seem a viable option to me.) -- Björn Höhrmann · mailto:bjoern@hoehrmann.de · http://bjoern.hoehrmann.de Am Badedeich 7 · Telefon: +49(0)160/4415681 · http://www.bjoernsworld.de 25899 Dagebüll · PGP Pub.
