```
    Description copied from class: Expr
    
    Evaluates the expression and returns the resulting item, or Empty.VALUE if the expression yields an empty sequence. If this method is not implemented, Expr.value(QueryContext) must be implemented instead.
    
    Overrides:
    
    item in class ParseExpr
    
    Parameters:
    
    qc - query context
    
    ii - input info (only required by Seq instances, which have no input info)
    
    Returns:
    
    item or Empty.VALUE
    
    Throws:
    
    QueryException - query exception
