Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The <menclose> MathML element renders its content inside an enclosing notation specified by the notation attribute.
