I don’t want to speak for Kim, but from what I understand of legal numbering and what was discussed rather quickly on previous calls, stressing the word “honor” helps the logic.  For example, just adding a 0 to all existing numbers allows 9 SC to be inserted between any 2, and would have very minimal disruption:

1.3.10 Info and Relationships
--> 1.3.15 New 2.1 Criterion
1.3.20 Meaningful Sequence

That’s just one technique of many.

Hi Kim,

I’m a bit confused, the logical result of:
> keep the numbers sequential,
> levels together, and
> honor (keep) the WCAG 2.0 numbers.

would be that we cannot add new SCs at A or AA, as either numbers would be out of sequence, or the levels would be.

Assuming we do add new SCs above AAA, we either have to re-order or re-number in some way, am I missing something?

My suggestion (for later) was that we de-emphasise the numbers and then allow them to be out of order, so that the levels are kept together.

Kind regards,
