+This product includes code from Delta Lake.
+
+* AssignmentAlignmentSupport is an independent development but was inspired by an equivalent rule in Delta.

Review comment:
       It was used as a reference. I did not simply copy the code as is so I added "inspired by" to give credit to the original authors. The rules should be logically equivalent and should be part of Spark, not data sources.
