POSITION is an int (say, n)
and refers to the nth child CST node.
When XmlPath_opt is empty, an ChildXmlTree refers to the XML element of the nth child CST node. When XmlPath_opt is not empty, it is a bracketed, dot-separated sequence of POSITION's (see XmlPath). This sequence denotes a tree-address path in the tree of XML elements, starting from the XML element associated with the CST node at position n.
