|
* The struct contains source and target XML tree (e.g. candidate/running)

* But primarily a set of XML tree vectors (dvec, avec, cvec) and associated lengths

* These contain the difference between src and target XML, ie "what has changed".

|
|
* It is up to the commit callbacks to enforce these changes in the "state" of

*the system.
