The dir="" is not really intended to specify that the direction is not known but that the direction has not been specified explicitly. For instance, in an aggregate feed containing entries from multiple sources, the original entries may or may not have contained the bidi attribute. Because of the inheritance of direction from the feed, entries that do not have a dir="..." attribute will inherit the direction of the parent, which will change the context of the original entry and could potentially lead to the context being improperly or at least unexpectedly displayed relative to the original. - James Frank Ellermann wrote: > Stephane Bortzmeyer wrote: > >> as I said, otherwise, you could not express the fact that the >> direction of the text in the <bar> element above is "Not Known". >> Without dir="", you could not "cancel" the directionality of >> <foo> in its nested elements. > > Well, yes, but so far the Web with all its (X)HTML pages never > needed an "unknown direction" feature, why is this necessary > in ATOM ?
