actions and the Mapper anchors can be in any sequence. You can also insert other actions in the sequence.
Notice that a Mapper uses
actions rather than Mapper anchors to write to the output XML. This may seem a little different from Parsers and Serializers, where the output is created by anchors and serialization anchors, respectively. Actually, this is just a terminology issue. The
action could have been defined as a Mapper anchor. It is defined as an action because it is useful in other circumstances, unrelated to Mappers.
