The current algorithm effectively says that you can have subdomain policies, or you can have relaxed alignment, but you cannot have both. This does not meet my definition of upward-compatible. However, if we are willing to deprecate major functionality in the pursuit of freedom from the PSL,

Seems reasonable. Thanks for the warning on the required white space engineering. Scott K On February 27, 2023 6:05:11 PM UTC, John Levine wrote: >It appears that Tim Wicinski said: >>-=-=-=-=-=- >> >>I agree that we should fix this tolerance in the bis document. > >I made a pull request.

I can not agree more than 100 percent on this. The PSL has issues. We need to stop depending on it. If anything, the PSD work has shown the W3C folks that there is a path forward for folks who need to do PSL-like things without boiling the ocean. tim (who has spent a bit too much time recently

Barry, I think you have forgotten that organizational domain is needed for relaxed alignment as well as disposition request. You cannot do relaxed alignment correctly unless you find and use the correct organizational domain. The current text has an incentive problem. For an evaluator, the
