Erik,
Sorry for the delay in responding. Let me try a very high-level
summary of the implications of what I, at least, consider the
most important history of the problem you are trying to bite off
a piece of (others will have other histories). First, it isn't
easy. Even if one just ignores the various flavors of
Informational documents, the right documentation rules for
single-stage processes (e.g., BCPs) are inevitably different
from those for two (and previously three)-stage technical
standards track ones. That problem is further complicated by
the fact that we use BCPs, and occasionally technical standards,
for what are really procedural or policy statement documents.
Second, there is a complexity tradeoff. Today, for normative
documents, we have BCP documents and 2 1/2 levels of standards
track one (depending on what one thinks Experimental is).
The issues of updating and categories are also inevitably
complicated by the nearly-orthogonal one of interrelated and
interdependent documents, some developed at different times and
by different groups and often with non-obvious overlaps.
We tried to take all of this on some years ago in a WG called
"NEWTRK". It was not successful. In particular (and trying to
state this as neutrally as I can manage), the WG concluded that
we needed a new type of Standards Track document that would talk
about status and relationships among documents, rather than
being one or more technical specification itself. At least some
of what you seem to be proposing would go into those
standards-description documents and not the technical
specifications themselves. In addition, at least some of us
believe that the relevant documents would be living documents
with change histories rather than the inherently-static (at
least per-document) RFC series.
WIthout revisiting the argument and various opinions about
motivations, the IESG concluded that the idea was just too
complicated and/or inappropriate and the idea when nowhere. In
retrospect, they might have been right. Or not. Either way,
the experience left many of us reluctant to start nibbling at
the issues again unless there was a comprehensive plan that the
IETF was willing to sing off on.
However, I do believe that it is unrealistic to believe one can
take on inter-document relationships without at least reviewing
the issues that the NEWTRK WG examined and the options it
considered.
best,
john
