In my opinion, the prose was intended to have the same or close to the same weight as the ABNF in terms of what constitutes a valid registry. While it is certainly possible to have created an ABNF representation of the registry that embodies all of the content requirements of the prose, such a representation would be cumbersome to create, maintain, and validate. For better or worse, the prose was used as the main vehicle of applying content requirements to the registry. The ABNF in Figure 3 is certainly very abbreviated (seven lines), whereas the full description of the file format, records, and their contents runs 13 pages... and there are VERY explicit MUST statements regarding the validity and content of records in section 3.5 spelling out that *all* requirements in RFC 5646 must be met before a submission to IANA can be considered completed.

I think changing the File-Date record sounds like an appropriate way to communicate that the registry has been updated even though no new/changed records have been introduced.
