The power of EXPLICIT mode is to mix attributes and elements at will, create wrappers and nested complex properties, create space-separated values (for example, OrderID attribute may have a list of order ID values), and mixed contents.

You can use some of the new FOR XML capabilities, such as writing nested FOR XML RAW/AUTO/PATH mode queries and the TYPE directive, instead of using EXPLICIT mode to generate the hierarchies. The nested FOR XML queries can produce any XML that you can generate by using the EXPLICIT mode. For more information, see Use Nested FOR XML Queries and TYPE Directive in FOR XML Queries.
