+ *  @class      dash::mpd::ITimeline
+ *  @brief      This interface is needed for accessing the attributes of <b><tt>S</tt></b> elements, as specified in <em>ISO/IEC 23009-1, Part 1, 2012</em>, section 5.3.9.6.1
+ *  @details    dash::mpd::ITimeline objects correspond to <b><tt>S</tt></b> elements of the <tt><b>SegmentTimeline</b></tt> \n \n
+ *              The <b><tt>S</tt></b> element contains a mandatory \c \@d attribute specifying the MPD duration, 
+ *              an optional \c \@r repeat count attribute specifying the number of contiguous Segments with identical MPD duration minus one 
+ *              and an optional \c \@t time attribute specifying the MPD start time of the first Segment in the series.
+ *  @see        dash::mpd::ISegmentTimeline dash::mpd::IMultipleSegmentBase dash::mpd::IMPDElement
