className
    One or several class names, separated by space. Multiple class names demands that each match have all of the classes specified. Mandatory.
tag
    Specifies the tag name of the elements to match. Optional.
elm
    Reference to a DOM element to look amongst its children for matches. Recommended for better performance in larger documents. Optional.
