Using EXPLICIT Mode provides more control and flexibility in deciding the shape
of the XML from a query result.
The EXPLICIT mode queries need to be written in a specific way so that the
additional information about the required XML, such as expected nesting in the
XML, is explicitly specified as part of the query.
Using PATH Mode with nesting is a simpler alternative to writing EXPLICIT mode
queries.
It needs to be ensured that the generated XML is well formed and valid because
the XML needed is described as part of the query in EXPLICIT mode
