    Remarks
    Hints are used declaratively. They tell LiveLinq query optimizer to create and use an index on this element, if possible. When the query is executed, the hint method IndexedElement is replaced with the standard LINQ to XML method System.Xml.Linq.XContainer.Element(System.Xml.Linq.XName). See C1.LiveLinq.Hints for more details.
    Example
    var query =
    from c in customers
    where (string)c.IndexedElement("CustomerID", IndexingHintAction.Mandatory) == "ALFKI"
    select c;
