But that's not what Paul said. I am sure we all agree the information _should_ be there, but I took Paul to mean that it _is_ there.
If I look at PDBe for 2gs7, go to Downloads and Structure Factors, then the cell and symmetry is _not_ there. If I go to RCSB, and click on Structure Factors on the RHS, same file, and cell/symm is _not_ there. 1f9j is another example. Really, there are lots. I am not going to report them all... There was also (last time I looked) a number of entries that had a CRYST1 card included in a cif comment section.

That information could even be enclosed by two commentary sections (i.e. '# Added by wwPDB mm-dd-yyyy hh:mm' and '####################') to highlight the changes.

My understanding is that these days they should have - and if you find such examples, they should be reported to the wwPDB authorities.
