   retained in this dictionary only to provide compatibility with
   old CIFs.

`G`	rigid-group refinement of site

`R`	riding-atom site attached to non-riding atom

`D`	distance or angle restraint on site

`T`	thermal displacement constraints

`U`	Uiso or Uij restraint (rigid bond)

`P`	partial occupancy constraint
