Hi Giuseppe,

The scope seems reasonable. My only comment is that (3) and (4) has dependencies to external W3C groups. My recommendation is to avoid creating a profile to future standards or activities. It should reflect what is currently available and supported. As things are adopted then they can be included in the profile and not before.

Regards,
JanL
