Type casting works as an alternate filter for data source elements. A cast query filters the results of the regular query to return only the elements that can be cast to the selected type. After the type is selected, it becomes available in the Data Source View under the anyType element. Queries built using cast allow access to all the child elements and attributes of the type cast. The result set returned by a cast query is identical to the result set returned by a query that is filtered with an equivalent IsKindOf predicate. The difference between the cast query and filtered query is that a cast query gives access to the cast type attributes and child elements while the filtered query does not.
