RSOBHD Rule Book
Publisher: Royal Scottish Official Board of Highland Dancing (RSOBHD)
Competition rules, age groups, dress code and championship steps. A 2022 edition circulates publicly via member organisations; RSOBHD remains active (2026 championship step documents published). Living document - record the edition. PRIMARY SOURCE for LODance style "highland-dance" (publication_status=research). Year deliberately NULL: these are living documents in numbered editions and a single year would misrepresent them — read and record the edition in force.
