Bunch of discussion going on in issue 264 https://github.com/KantaraInitiative/wg-uma/issues/264. Issue 263 https://github.com/KantaraInitiative/wg-uma/issues/263 is somewhat related though it's seen no discussion yet, so I'll take the opportunity to mention it here. I think we can figure out both of these by next week (said the optimist). *Eve Maler*Cell +1 425.345.6756 | Skype: xmlgrrl | Twitter: @xmlgrrl
