Source and destination with identical OCMs
If the source and destination content models are identical, then the resulting destination sub-tree is identical to the source. All elements are copied to the destination maintaining their relative position in the sub-tree.
Child elements are added to the destination. This applies when the content model for the destination contains matching element names to child elements that exist in the source.
The XML content model can contain anonymous nodes that do not refer to an
actual element in the XML message. These anonymous nodes are not matched in the
PATHCOPY
operation; instead, their children are matched, unless the
child is also anonymous.
