One possible approach is to remove that negative checkpoint from each
dimension, but have a pointer in each across to something in GL 10:
"If [this dimension] is not used, make an explicit statement of non-use
per the provisions of Checkpoint 10.x." Then, part of Ck 10.x says:
"For each of the following specification techniques that is not used,
state that fact explicitly: multiple classes of product, profiles,
modules, degrees of conformance, deprecation, levels, discretionary
choices, extensibility, and open-ended discretion to support languages,
locales, etc." (rough wording to convey the general idea)

This way, a person bent on implementing or testing the spec can start
from the table of contents, navigate to conformance verbiage, and find
out what variability exists, as well as those dimensions that are
designated as invariant.
