The XUA profile has been updated with a few use-cases where we found mature standards and production interest in using these capabilities. There are a larger set of use-cases that we looked at satisfying, but found either no interest from production environments or not sufficiently mature standards. The hope is that over time there will be more demand for these use-cases and there will be more experimentation with the available standards. Once these use-cases mature we will address them. For those that are implementing these unaddressed use-cases now, please let us know. If we have sufficient evidence of a production need and mature standards then we can roll these use-cases into the post Public Comment phase.
