This one needs discussion, and I'd rather avoid telecon time on it if possible, so let's please discuss it here: https://github.com/KantaraInitiative/wg-uma/issues/275 There are three problems. - The structural problem is that the error_details structure is always optional, but that's where ticket lives. This could be fixed by moving ticket just outside of error_details. - The spec text problem is that it's underspecified when ticket is supposed to appear. It MUST appear when the AS responds with need_info, and it MUST NOT appear otherwise. - The example problem is that we've got a need_info example that doesn't show a ticket in it. That's easily fixed once we're certain how to fix the other two. Any disagreement/discussion on any of this? *Eve Maler*Cell +1 425.345.6756 | Skype: xmlgrrl | Twitter: @xmlgrrl
