missing parent small non-coding RNA-dependent heterochromatin formation

[ValWood]

GO:0031048 small non-coding RNA-dependent heterochromatin formation

should be a parent of GO:0140727 siRNA-dependent pericentric heterochromatin formation

or probably even GO:0031508 pericentric heterochromatin formation (since I think pericentric heterochromatin formation always depended on siRNA? do we know of any examples where it isn't?)
