Hello David, Brian,
Just want to make it clear. David's suggestion refers to the XSLT
transformation. However the original question (as far as I understand
Brian's posting) referred to the XSL-FO rendering (in particular to
the page numbers produced by formatter). XSL-FO rendering stage is
completely independent from XSLT and there is no "tags" you can place
in XSL-FO to make formatter produce special log messages. That's why
I'm saying "no".
Still we need more input from Brian to make further suggestions.
Best regards,
