In designing XHTML 2.0, the HTML WG coordinated with the I18N WG/IG for a better design, and came up with the single "dir" attribute with 4 possible values, namely "ltr", "rtl", "lro", and "rlo" [2]. IMHO, this is simpler than the current ITS design. The OASIS DocBook TC also coordinated with them on adding BIDI support to DocBook and agreed to use the same design as XHTML 2.0, and DocBook V4.3 and later incorporated it. The I18N Activity also extended the XMLspec DTD this way to allow BIDI override markup for their spec work [3]. Since a couple of existing/emerging vocabularies are already migrating to this design, I would suggest that the ITS WG consider this design as a possible ITS markup for dealing with bidirectionality.

At the Oxford f2f, we said we still have to check if there are other possibilities, but we can do that later. I just don't want to let Mimasa (or other commentors) wait too long. Is anyone against this? Regards, Felix. 7812 2 fsasaki 2006-01-13 03:07:23 +0000 The working group decided to follow Mimasa's proposal.
