+    * \brief AVOID using the following fourth field at all costs.
+    * 
+    *  They are at leat two good reasons for NOT using fourth:
+    *  - the main reason is that it is NOT part of the 'official'
+    *    Dicom Dictionnary.
+    *  - a second reason is that it is not defined for all the groups.
+    *  .
+    *  Still it provides some semantics as group name abbreviation that
+    *  can prove of some help when organizing things in an interface.
+    *  For the time being we keep it in gdcm but it migth be removed in
+    *  future releases it proves to be source of confusion.
+    *  Here is a small dictionary we encountered in "nature":
+    *  - CMD      Command        
+    *  - META     Meta Information 
+    *  - DIR      Directory
