I agree that the charter defines that the AR vocabulary is separate from
the core POI recommendation.  Here's the exact text:

        The Working Group will deliver the following documents:
        Points of Interest Recommendation
                This Recommendation defines a format for the common
                components of a Point of Interest 
        Points of Interest: Augmented Reality Vocabulary
                This Working Group Note specifies a vocabulary of
                properties to enable Augmented Reality applications by
                attaching additional information to POI data, e.g. logo,
                business hours, or social media related properties

But it's the "by attaching" bit that has been completely missed.  At the
moment I can't see a clear mechanism for doing this.  Link doesn't
really meet that need.  Metadata doesn't either.

Without a clear mechanism then we can never move on from the first phase
without having to revisit it.
