Andrew,
The idea is that the Dublin Core spec will in some sense be evolving
more quickly than the RFC process can track. This doesn't mean that
the basic elements are expected to change, or even that qualifiers
are expected to change that often. Rather I think it has to do with
tracking current practice on things like exactly which language spec is
the default (ISO 639-2 or RFC 1766), or what strings you use to specify,
say, the three most popular controlled vocabularies for Subject, etc.
