Currrently with LaTeX2e packages and classes, only LTR typesetting is considered and there is no attention for RTL typesetting, so I was just wondering if you guys are going to consider RTL typesetting in LaTeX3 and design some classes for RTL typesetting? Currently There are lost of changes that needs to be done to normal LaTeX2e classses (like article, report and book) so that they will support RTL typesetting properly. So will RTL typesetting be considered in the LaTeX3?
