Filed from MTN via HVQ then via the HVQ transition on the RAVNN5 to MTN. We were cleared as filed. Once enroute we were asked by center what part we were operating under. The question was ambiguous so I asked for clarification. Center replied and asked what part we were operating under and if we were authorized for the RAVNN5. I replied that we were Part 91 and we were capable of flying the arrival. At that time we pulled the STAR chart on the MFD and reviewed it. Upon examining the notes closely; I saw that note 5 stated 'All Part 91; 101; 103; 105; 125; 133; 135 and 137 flight operations are prohibited on the Beckley/Charleston transition. As I was about to advise ATC that we needed different routing; they called us with a reroute via direct ESL then MRB for the EMI5 Arrival. We reprogrammed the FMS and continued the flight without event.There were several factors that I feel led to this: First; the note on the Jeppesen STAR chart is very ambiguous and should say 'Part 121 operators only on Beckley/Charleston transitions' .  Also; the note should be near the route on the chart. ATC should have been more clear in their query about our route. Asking 'what part are you?' is not clear. Lastly; we (the crew) should have reviewed the STAR chart prior to departure rather than rely on past experience with this procedure. We fly the RAVNN5 routinely; although this was the first time we had flown it from this direction. Because we had flown the arrival many times; we didn't review the notes; only the route and altitudes.
A Part 91 Corporate jet crew filed to MTN on the RAVNN5 HQV transition but they were informed by ZID that only Part 121 aircraft are permitted on that transition and so refilled the flight ESL; MRB and the EMI5 Arrival.
