This returns a Boolean depending on whether the list is empty. In this context Set and List type can be regarded as interchangeable. If empty, the return value is true, if the attribute has content then false is returned.

$MyList = [hello;world]; $MyBoolean = $MyList.empty; 

$MyBoolean is set to false as content is found. But

$MyList = []; $MyBoolean = $MyList.empty; 

$MyBoolean is set to true as no content is found.
