Source and destination with different OCMs
When the content models are not the same, a matching algorithm is used to
match the source elements with elements in the destination content model. The content
models must be similar for the matching algorithm to work. A value that is retrieved from
the source is copied to the destination if a compatible path can be identified in the
destination content model. This path is constructed from the starting point of the PATHCOPY
to the #text
node.
