You mean absolutely positioned AT blocks, not fo:blocks? Right, I thought I'd do something like that. It'd be hard to solve at the FO level at any rate, for corner cases like tables, indented/nested blocks or variablelists. Do you mean that this is a sort of confirmation of the proposed method, that you are doing something similar? I tried just blindly adding a new attribute to my FO blocks but FOP-trunk choked on that because it did not recognize the foreign attributes. So I assume I'll have to handle them somehow specially? I seem to remember an old mail discussion that mentioned using ID attributes, maybe that is a way forward?
Yes thats right. Using the ID attribute is the way to identify what elements in the AT or IF XML came from which fo:blocks in the source. Up until recently this trick only worked in AT, but Vincent recently committed a change to trunk to support this in IF XML too.
Has anybody else experimented with having custom information fall through to the intermediate formats in general? /F

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?
