If there is no standard for the validation checks logs perform, because of a desire to accept malformed certs from (sloppy) CAs, then a CA cannot know whether its submission will be rejected by a log. The alternative is to specify a way for each log to specify what checks it performs, and to publish that the same way other
log info is advertised.

#73: Section 3 text re log cert validation is ambiguous


Comment (by [email protected]):

  On the issue of specifying deviations, I am not sure how that could
  realistically be done. For example, our logs will permit whatever
  deviations OpenSSL permits. I don't think anyone knows precisely what
  those are, and I'm prepared to bet they vary between versions.

  Even leaving that aside, experience suggests we have to permit deviations
  in order to admit incorrect certificates that are accepted by browsers. I
  don't think we can anticipate what all of those are.
