/** Class managing an SR document tree that is based on an SR root template.

 *  and should be used for root templates only.
 ** @note The main focus of this class currently lies in the creation of SR documents that
 *        are based on an SR root template.  Support for reading SR documents into the
 *        underlying structures might be added in the future.
