Hello Jacques,

Thank you for responding to the invitation from Rob.

Do you think it is possible for you to prepare a position paper for the 
upcoming International AR Standards Meeting on the topic of the AR 
framework which you have in mind?

I understand that you are unable to attend in person, however, it would 
be great to have a contribution from you as we will also have from 
Thomas Wrobel and others who are unable to be in Seoul on Oct 11-12 for 
this meeting [1].

The instructions for paper preparation are here [2]

Thank you for your time.
