The MathML spec says, "In practice, typical renderers will only be able to stretch a small set of characters, and quite possibly will only be able to generate a discrete set of character sizes." It is quite likely that whatever problems Prof. Hutchinson pointed out are those of the renderer he was showing, not MathML. Also, in cases where the default behavior of MathML is not desired, MathML allows control over how large or small the character should be (within the constraints of the renderer). Also to be noted is that Prof. Hutchinson is a proponent of MathML, not a opponent -- he authored one of the leading TeX to MathML converters (TtM), and MIT (or at least the Information Services and Technology Department) endorses the use of MathML: http://web.mit.edu/ist/topics/webpublishing/mathml/index.html > > Rendering of large brackets requires positioning of bracket-fragment > > characters > > There is no such one requirement. All of the math typesetting systems that I am aware of that have had widespread usage the last 40 years use fragments for laying out parens, etc. Stretching a paren or using a large font size results in unacceptably poor looking results. If you have a system for math typesetting and it doesn't allow positioning of bracket fragments, either it relies on some new font technology or is producing math display whose quality has been deemed unacceptable in the past.
