Proposals approved for inclusion into the C9X draft, stage 4:
N873 (02/99) Disposition of comments
Proposals with final words approved for inclusion into the C9X draft
that have not yet been applied, stage 4:
Proposals principally approved, final wording to be drafted by review
committee, stage 3:
Reminder of what the stages mean, the stages only give the state the
proposal is in. Proposals can skip stages. This is adapted from N556
and N585 as accepted at the June 96, Amsterdam meeting:
Stage 1 = proposal w/o technical details requesting interest from WG14
for development of a technical proposal.
Stage 2 = technical proposal, ready for consideration by WG14.
Stage 3 = principally accepted, for inclusion into C9X. At this stage
the exact C9X changes must be drafted and edited by the
review committee. After review, the final C9X changes are
to be included in a mailing for final approval by WG14 for
inclusion into the C9X draft.
Stage 4 = accepted by WG14 for inclusion as is into C9X. The proposal
contains the specific editing instructions to change the C9X
draft, and is ready to be included in the next C9X draft.
Stage 5 = changes applied to the latest C9X draft.
Stage 6 = verified by the review committee as being correctly applied
in the C9X draft.
