|---|
| 14 | * normal loops always start and end with a SEGMENT |

| 21 | * version 2 had DELTA and DELTA_IN (loop->strand-angle (rootside) and reverse strand<-loop-angle (outside)) |
|---|
| 22 | * version 3 has REL entries in STRAND _and_ LOOP. These angles are relative to angle of father element. |
