Hey, I'm trying to make a workaround for the lack of change bar support in FOP. I was thinking about making a two-pass solution that analyzes the area tree and adds additional content where necessary. I have really modest needs so maybe that could be workable. * No nesting, only one class * Just thin simple black lines, ok if they overlap since that won't be visible * Always positioned on the exact same x-position relative to the left page margin * Just apply on entire building blocks (such as paragraphs, a title etc)
However, that would need some form of tagging in the AT, that is lifted from the transform stage. That is, ideally I'd like to be able to add a myns:changed="true" attribute to my input docbook blocks, and that would result in <block> elements in the AT that are decorated in such a way that I can pick it up. I can't just add a border-left at the fo level though, because the changed blocks might be part of a variable list or other types of elements that aren't flush with the left edge. Has anybody done something like this? Does it sound silly? Any other suggestions for workarounds? Regards, /Fredrik
