示例1: Apply
/*
WITHIN evaluates to TRUE if the right-hand-side first value contains
the left-hand-side second value (or name and value) as a child or
descendant (i.e. directly or indirectly). If either
of the input operands are missing, return missing value, and if
the first operand is not an array and the second is not an object
return a null value. Range through the descendants of the second
value object, and check if the first value is equal to each
descendant; return true. For all other cases return false.
