(Copying Doug as I am not sure whether this is a concern of the FXTF or the SVG WG proper) Currently, CSS3 Text Layout defines the writing-mode property as taking: lr-tb | rl-tb | tb-rl | bt-rl | tb-lr | bt-lr In SVG1.1, Second Edition [2], writing-mode supports : lr-tb | rl-tb | tb-rl | lr | rl | tb | inherit 1) In addition to the inherit keyword, SVG adds shorthand values for lr-tb (lr), rl-tb (rl) and tb-rl (tb). 2) SVG also drops bt-rl, tb-lr and bt-lr. To make both authors and implementors lives easier - especially in mixed documents - both WGs should harmonize the values this property supports. At a minimum, I propose that the CSS3 definition of writing-mode: 1. Include the inherit keyword 2. Include the shorthand values defined by SVG i.e. lr, rl and tb. I suspect SVG drops certain direction combinations due to the lack of known script for them but those may be useful for other purposes.
