Description Felix Sasaki 2005-11-24 13:15:02 UTC
Original comment from Mimasa, cf. :

"4.4 Directionality" [1] of WD-its-20051122 defines the "dir"
attribute and an optional "bdo" attribute, analogious to
HTML 4's "dir" attribute and the bdo element.

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

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.

Comment 1 Felix Sasaki 2006-01-08 04:35:17 UTC
I would propose to follow Mimisas suggestion for four values. 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.

The working group decided to follow Mimasa's proposal. The underlying markup
definition can be found at .
