There's two things that distinguish HSLs/LGVs/NBSs: high maxspeed (typically 250-320, though some would include the new lines in Switzerland, which are "only" 200), and a lack of slow traffic (freight, stopping passenger services) because they have alternative routes.
In some cases, you can get pretty high speeds without providing a second pair of lines, if traffic is sparse (upto 200kmh in the UK, upto 230kmh in Germany), so I think the presence/absence of a parallel slow route is something that can usefully tagged explicitly.
