/**
- * \ref DocEntrySet is an abstract base class for \ref ElementSet
- * and \ref SQItem which are both containers for DocEntries.
- * \ref ElementSet is based on the STL map<> container
- * (see \ref ElementSet::TagHT), as opposed to \ref SQItem
- * which is based on an STL list container (see \ref ListDocEntry).
+ * \brief
+ * \ref DocEntrySet is an abstract base class for \ref ElementSet, \ref SQItem
+ * which are both containers for DocEntries.
+ * - \ref ElementSet is based on the STL map<> container
+ * (see \ref ElementSet::TagHT)
+ * - \ref SQItem is based on an STL list container (see \ref ListDocEntry).
+ *
* Since the syntax for adding a new element to a map<> or a list<>
* differ, \ref DocEntrySet is designed as an adapter to unify the
* interfaces of \ref DocEntrySet and \ref ElementSet.
+ *
* 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 Document::ParseDES
- * which calls \ref Document::ParseSQ, which in turns calls
+ * which calls \ref Document::ParseSQ, which in turn calls
* \ref Document::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.
