Dear MathML developers, as some of you are aware of, our group is doing research on mathematical notations. In the MathML 3 spec, chapter 4, you give a "default rendering" for each Content MathML symbol or constructor. For our research it would now be interesting to learn from you: Where do these default renderings come from? How did you agree upon one rendering when you had to choose between more than one? For example: Why did you choose (0,1) for an open interval instead of ]0,1[? Why ĝ for the empty set but not {}? Why \subset for the proper subset but not \subsetneq? Why f' but not df/d? -- Note: Of course I don't expect an answer for every individual case, but some hints on your general intuition or strategy would be helpful. Thanks in advance, Christoph -- Christoph Lange, Jacobs Univ. Bremen, http://kwarc.info/clange, Skype duke4701
