Ah, thanks for clarifying. I think that, barring some consideration not
taken into account, then either of these two solutions work.

1) Corey's solution:
  - 1 extension for DNS validation methods
  - 1 extension for IP address validation methods
  - Looking at the CT logs, I see there's only 482 certs/precerts in CT for
the period 2018-01-01 to 2018-08-10 with both DNS & IP addresses, compared
to 209,560,065 entries for that same period (note: this includes compliance
monitoring certs)
2) Assigning a distinct ID for each validation method within the respective and sections
  - That is, the IP address section may say "The ID of this validation
method is 17"
  - A newly added DNS method may say "The ID of this validation method is

I think an informative (non-normative) table can benefit Approach 2, but
that could be managed as part of the change process (e.g. "ID method 17
refers to method, introduced in BRs 1.6.9 and removed in BRs
1.9.2" or the like), but that's not essential. Happy to help draft text to
demonstrate that, if it would help.
