Hi Peter,

On 11/09/2010 04:15 AM, From Peter Saint-Andre:

I apologize for the huge delay as I'm fighting a flu and a huge backlog. 
I believe the wording is still a bit strong since "SHOULD NOT" means you 
really should *not* except in very specific circumstances exceptionally.

My opinion is, that with good constraints in place (that is contractual, 
proper validations of the applicant etc.) wild cards should be 
legitimate in every respect and there are many good examples for those 
(remember XMPP?). From the CA perspective, the CA really MUST have 
controls in place to prevent misuse, however if the CA will issue 
certificates for paypal.domain.com the argument against wild cards is 
obviously moot.
