/**
* Description:<br>
* The structure node (ST) is used to build structures in the course hierarchy.
* In addition it is also used to calculate score and passed values, to syndicate
* these values e.g. from children nodes. Example: a lesson with two tests is
* passed when both tests are passed. This would be designed as an ST node with
* two IMSTEST nodes as children and a scoring rule on the ST node that syndicates
* the testresults. In the assessment tool the ST node results can be seen but not
* changed since these are calculated values and not saved values from properties.
