When upgrading Jmol to handle the new magCIF format, I spotted something I was not expecting - a syntax that broke Jmol's CIF reader:

loop_
  _parent_propagation_vector.id
  _parent_propagation_vector.kxkykz
  k1 [-0.75 0.75 -0.75]

To all accounts, this looks to me like CIF 2.0 format.

I'm pretty sure I saw in the CIF 1.0 specs that "[" at the beginning of an unquoted string is reserved -- I suppose just for this -- but I can't seem to find where this would be in the specs.


Can someone explain?

Bob Hanson
