+/**
+ * \ref gdcmDocEntrySet is an abstract base class for \ref gdcmElementSet
+ * and \ref gdcmSQItem which are both containers for gdcmDocEntries.
+ * \ref gdcmElementSet is based on the STL map<> container
+ * (see \ref gdcmElementSet::TagHT), as opposed to \ref gdcmSQItem
+ * which is based on an STL list container (see \ref gdcmSQItem::docEntries).
+ * Since the syntax for adding a new element to a map<> or a list<>
+ * differ, \ref gdcmDocEntrySet is designed as an adapter to unify the
+ * interfaces of \ref gdcmDocEntrySet and \ref gdcmElementSet.
+ * As an illustration of this design, please refer to the implementation
+ * of \ref AddEntry (or any pure virtual method) in both derived classes.
+ * This adapter unification of interfaces enables the parsing of a
+ * DICOM header containing (optionaly heavily nested) sequences to be
+ * written recursively [see \ref gdcmDocument::ParseDES 
+ * which calls \ref gdcmDocument::ParseSQ, which in turns calls 
+ * \ref gdcmDocument::ParseDES ].
+ *
+ * \note Developpers should strongly resist to the temptation of adding
+ *       members to this class since this class is designed as an adapter 
+ *       in the form of an abstract base class.
