The writing mode specification makes a note about this inconsistent use of left / right on several properties, including 'text-align' [1]. The CSS properties left / right are physical and the writing mode specification seems to make a similar statement about the left / right values by adding a more precise vocabulary (line-left/line-right) as well as singling out some older, un-precise uses. Having 2 incompatible meanings for left/right is confusing and it would be an opportunity to clarify that. Julien [1] http://dev.w3.org/csswg/css-writing-modes-3/#line-mappings
