RE: [MathML4] Deprecation/Removal of the mfenced element

Hmm. I like <mfenced>. It's an element that says up front what it means. <mrow> is abstract and requires parsing before you know what it means. In Microsoft Office math, there is the "delimiters" element <d> that maps neatly into <mfenced>. The LineServices math handler formats such elements automatically expanding to fit their arguments. The result is math typography very much like TeX, but without the need for control words like \biggl.



Our products can generate and input MathML using <mrow> instead of <mfenced>, but parsing similar to that used for the math linear format<http://www.unicode.org/notes/tn28/UTN28-PlainTextMath-v3.pdf> is used to convert to <d>.
