Gary, I provided the link in the original email: https://github.com/apache/xalan-java/blame/master/src/org/apache/xalan/xsltc/compiler/DocumentCall.java
compare it with a much better one (pay attention to commit ids to the left of the line numbers): https://github.com/apache/xalan-java/blame/xalan-j_2_7_1_maint/src/org/apache/xalan/xsltc/compiler/DocumentCall.java You can try the same locally: git blame src/org/apache/xalan/xsltc/compiler/DocumentCall.java In master branch the command prints "356ce496f (Mukul Gandhi 2023-04-14" for every line of the file.
