Hello all,
 
Please find attached ARX's contribution towards a profile for visual

The attached document is by no means complete or fully specified - it
should be viewed as a basis for further discussions.
Please start by reading section 3 which describes some of the key
aspects of the proposed profile as well as motivations and use cases.
