Er, no. Specs are always a subset of the complete set of user requsted features. Specs that aren't are a nightmare (see SVG 1.2). Logical properties have been proposed in the context of vertical text as a way of simplifying the task of an author trying create vertical and horizontal layouts with a shared stylesheet. HÃ¥kon is merely asking whether this approach is the best way when this many new properties are required. You seem to be demanding a particular solution when you should be showing why logical properties are the better solution. > Your opinion is an excuse from an incompetent implementor. No, it's the concern of an implementor who has a long history of developing browsers for devices that run with restricted memory. John Daggett
