+/// \brief TagKey is made to hold an "universal" (as in URL, Universal
+///        Ressource Locator)  key to a DocEntry i.e. a dicom tag.
+///        A dicom tag always has a group and an element, but a set of tags
+///        embeded in various (optionally nested) sequences and sharing
+///        the same group and element all share the same (group, element)
+///        "identifier". Hence the (group, element) cannot be used as an
+///        identifier (in gdcm we shall refer to a "TagKey") of a tag.
+///        In order to construct a proper tag identifier (i.e. a key) we
+///        consider the following definition of a TagKey:
+///        - let Group, Element be the string representation of the
+///          group and element dicom tag members,
+///        - let ItemNumber be the string representation of the integer
+///          index of the considered item number of a sequence,
+///        Let the key of a tag embeded in a sequence, noted SeqTag, be
+///        the form:
+///           /ItemNumber#Group|Element
+///        where "/", "#" and "|" are characters acting as separators.
+///        Then the general form of a TagKey is given by:
+///           Group|Element[SeqTag]
+///        where [SeqTag] means NO or many instances of SeqTag.
+///        Hence the TagKey of a tag not "leaving" in a sequence is the
+///        string e.g. 
+///            0028|1201
+///        but the TagKey of a tag "embeded" is the first item of
+///        a sequence, itself nested in the third item of a sequence is the
+///        string e.g.
+///            0004|1220/2#0008|0082/0#0008|0090
