I think the cases (2) and (3) are quite common... === Concerning another case: XML or XML-like documents where the direction *is* given by the "dir" attribute. While HTML is capable of controlling directionality by the *standard* "dir" attribute and not making use of CSS, does XML have such a capability, too (without developing its own markup)? In order to express the directionality, should a "normative" XML be compliant with the Internalization Tag Set Recommendations (which implies using "its:dirRule" element/ "its:dir" attribute)? https://www.w3.org/TR/its/#directionality Thanks, Lina
