== Summary ==
Input of the transformation script is the XML document of which a fragment should be extracted. Parameters of the transformation script are:
* ms1Name (first milestone name: e.g. "pb")
* ms1Position (first milestone position: e.g. 5)
* ms2Name (second milestone name: e.g. "pb")
* ms2Position (second milestone position: e.g. 6)
It returns an xml fragment between two milestone elements. The result sequence is wrapped into a parent element node.

== Restrictions ==
* uses the Saxon extension function [http://www.saxonica.com/documentation/extensions/functions/evaluate.xml "saxon:evaluate"] (so the Saxon library is needed for this)
* takes no care about namespaces
* wrapping into parent node cannot be configured
