Happy New Year to all MathML folks, I've just had a look to the new "directionality" feature of MathML 3 and I've some remarks: - In section 3.2.2, it is indicated that "MathML includes two mathematics style attributes as well as a directionality attribute valid on all presentation token elements, and on no other elements except mstyle.", but apparently they are all valid on the <math/> element and dir is also valid on <mrow/>, according to what is said elsewhere and according to the RelaxNG schema. - Moreover, if I read the RelaxNG schema correctly, the dir attribute is included in TokenAtt, itself included in mglyph.deprecatedattributes. Hence the <mglyph/> can theorically have a directionality. However, this seems to be a mistake in the schema since the spec says nothing about this possibility. - Finally, it seems that allowing dir on the token element <mspace/> is useless, because this element is empty.
