Thanks for the response.
Looking at the WCAG, there are only two numbers, such as in the example in
my original message 13.10.  There is no 13.10.1, etc. in WCAG, so I'm kinda
wondering where the 3rd digit comes from.

Initially, I could see where the 4th digit is just a sequential number in
the checks, but there are large gaps between them, suggesting this isn't

I guess the bottom line is, is there any important information to be gleaned
from these 3rd and 4th digits?
