Subject: Re: [office] Appendix on Bidi
Daniel, all, thank you very much for your proposal. I have taken this one and the various other e-mails regarding this topic, and some additional explanations I got from my colleague Frank Meies, and have created an BiDi appendix document. The document is located at http://www.oasis-open.org/committees/download.php/18504/06-06-01-bidi-appendix I think it addresses most of the BiDi related comments we received from Egypt, Israel and the UK. I further would like to propose that we include this appendix (or a revised one) into the OpenDocument 1.1 specification.
