Thanks for the comprehensive reply Jean-Marie! I recommend you add your reply to the OpenOffice::OODoc::Intro page as I think it probably covers a bunch of different non-standard page layout issues. In terms of the cookbook, would it be a good approach to have a note on each module page requesting submissions? With respect to my two-columns question, I'm wondering if a helper-application (written in Perl of course) could be written which could generate the code required to create or alter more complex documents with custom layouts. Perhaps a simple option-driven system which provides the equivalent capabilities of the various formatting dialogues in OOo itself. This would serve as (a) a useful development tool, (b) a testing framework to confirm that the module produces ISO/IEC 26300 compliant documents, and (c) a comprehensive illustration of how the module can be used at a low level. You've clearly done a great deal of work -- thanks very much!
