Re: Regarding publishing SDP-US as a Note vs Rec

those profiles are neutral to application, while this one is not; in
addition, this one goes beyond TTML into other player environment
constraints, e.g., end user style overrides; plus this one is region
specific; i'd prefer to segregate the region/application neutral part and
its region/application-specific profiles; plus there is an issue of
maintenance and versioning, which is harder if they were integrated
