Hi Frederic. For menclose the main attribute we need to support is notation which has different values such as box, circle etc. So for the implementation what I thought was we can create the element and while parsing the attribute if values are like left, right, top, bottom, acturial, madruwb, rounder box we can add CSS border properties. For radical we can create RenderMathMLSquareRoot as anonymous parent and for circle, updiagonalstrike, downdiagonalstrike, verticalstrike, verticalstrike, longdiv we can take care in paint of menclose.

Please suggest?
