Re: more about PDB Z value

I don't think that one would actually be revising the core CIF
definition in any way, just allowing the mmCIF definition to
cover a case which is exactly parallel to the small molecule
definition, by taking the entity definitions as the functional
equivalents of formulae.  The macromolecular case is fuzzier
than the small molecule case, but the PDB Z happens to match
the wording of the _cell.formula_units_Z if one adds entity
definitions as formulae.
