2. Due to the differing purpose of the PSL, there are cases where the correct
data for the PSL is not the correct data for DMARC (see the recent message
from John Levine with examples).
No, the PSL results are correct for those examples. The point of those
examples is to show that the relaxed alignment rule:
Two identifiers are aligned iff their org domains coincide
cannot be shortened to string comparison. It is necessary to find the org
domain of each identifier and then compare them. However, it is not clear
under what conditions the org domains found by the tree walk are the same as
those found by the (full) PSL.
