From: Adam Roach <[EMAIL PROTECTED]> At the risk of further bloodying the corpse of this poor horse, I still think the usage of feature tags in outbound is way, way off in terms of the semantics described in 3261.
You're completely right, of course. Why are we doing this so very, very wrong? It's almost as if we've gone out of our way to violate both the spirit AND the law of feature tag handling in as many ways as possible. And outbound is not the only place this has happened. It took a long time to purge this sort of error from gruu as well. IMHO, I think the reason is that people intuitively want "Supported" to mean "this message is invoking the feature in question" (which is ambiguous as to whether it means that the message contains use of the feature, or that the message requests the far end to apply the feature). People seem to have a hard time grasping that its purpose is to communicate a property of the UA, namely that the UA supports the feature in question. But many people in the world of software don't grasp talking about "properties that things possess", they can only talk about "actions happening right now".
