The MathML REC describes:

The menclose element renders its content inside the enclosing notation

specified by its notation attribute. menclose accepts any number of arguments;

if this number is not 1, its contents are treated as a single "inferred mrow"
|
|
containing its arguments, as described in Section 3.1.3 Required Arguments.
