Ballot 169 identified exactly 10 methods. Although this ballot passed 
unanimously, meaning that both CA members and Browser members on the whole 
supported these 10 methods, subsequently the CA/B effectively undid the changes 
from Ballot 169 because of patent concerns.

Mozilla's position as I understand it is that regardless of what happens with 
patents, they don't want CAs to continue inventing their own ad hoc validation 
methods (witness the flaws in the method GoDaddy came up with). Thus, even 
though some of the methods from Ballot 169 are not included in the Baseline 
Requirements today, Mozilla intends to oblige root programme members to pick 
from those ten methods.

So far as I can see three factors might cause a CA to decide it's necessary in 
their opinion to reject any particular method. These are

1. The method isn't allowed for them under the BRs, or another root programmes 
rules.

2. The method is subject to patent or other legal rights and they're unable or 
unwilling to agree acceptable terms to use the method.

3. The method is incompatible with the CA's business model or doesn't meet 
their own standards for validation.


For (1) I believe the BRs currently allow all ten Ballot 169 methods because 
they have an "any method" escape clause. If a CA believes another root 
programme requirement conflicts this would be the right forum for the CA to 
tell Mozilla about it.

For (2) where a CA is aware of such rights and they weren't already revealed to 
the CA/B it'd sure be helpful to know about them here.

For (3) I don't see any problem unless the CA rules out all ten methods. If any 
CA is on the verge of doing that they should definitely reach out to us in 
m.d.s.policy to explain their thinking.
