I had a quick look and yes this is very related to what we are doing. You
obviously have done all the schema work for a wider range of configuration
parameters. We have focussed on AR and have defined another much shorter
list. Are your schemas public? What is the status of the standard?

One thing we are also looking at is the distribution of the information.
Does ATSC have the intention of standardising on that too?
