With apologies to Nick for the delay, I have now posted the latest draft of the revised CIF specification change document (dated 18 February 2010) at http://www.iucr.org/__data/assets/pdf_file/0005/40775/syntaxchangesproposed20100218.pdf Nick has drawn my attention to the approach taken in this draft that many of the restrictions required to CIF2 data files and names that have been previously discussed on this list are a requirement of the DDLm application of CIF2. Hence this document is liberal with respect to what you can have. It allows for a family of CIF2 applications that imposes minimal name restrictions, *but such applications cannot be handled in a DDLm, dREL framework*. The implication is that if, for example, IUCr journals or other stakeholders wished to take full advantage of DDLm/dREL (which, after all, is the primary motivation for this line of development), they would impose the additional necessary naming restrictions to ensure that only DDLm/dREL-compliant CIFs were handled in their normal workflow.
