In some of the documents quoted there, I find an amount of places where MathML-content would need to support language, for example, that a content-symbol should support an xml:lang attribute. I really don't understand this! That a presentation template (i.e. a recipe to produce presentation from content) bears something such is clear but not the MathML-content itself ! > However, in our paper we note that there are more parameters than just > language that determine the correct choice of a specific rendering > during localization of Content MathML. > Among these, the most important parameter in our application is > probably the choice between rendering an expression as a formula (e.g. > "Vx.P(x)") or rendering it as natural-language text (e.g. "there is an > x such that P(x)").

Your points are valid and it goas as fine-grained as the classroom or course... Actually, if the rendering engine is used by an autonomous learner (e.g. a researcher), there's no reason customization of the notation is not offered for him as well. > It is in this context that MathML 3.0 will hopefully have better > support for marking choices between variants. But where, oh where, in MathML-content or in OpenMath would you like to put such choices ?? paulReceived on Thursday, 28 April 2005 18:18:40 GMT
