PrintFile filein=gdcm-MR-PHILIPS-16-Multi-Seq.dcm level=2
shows :

-> 7 levels of embedded Sequences ...

-> Inside the Private 'true length' Sequence :

S 0029|263d lg :     x(7088) 28808    [SQ]  (starts at offset  x(1b4a) 6986 )

   there is a 'true length SQItem'
   V fffe|e000 lg :     x(7080) 28800  [UL]  (starts at offset  x(1b52) 6994 )

      inside, a 'true length' Sequence
      S 0029|2a06 lg :      x(116) 278    [SQ] (starts at offset x(1bda) 7130 )

		   inside, a 'true length SQItem'
			V fffe|e000 lg :       x(2c) 44    [UL] (starts at offset x(1be2) 7138)
	      that contains ( at offset  x(1c02) 7170) the *impossible* tag :
         V fffe|0000 lg :        x(4) 4        [UL]
			It's taken as a group length, some oddities occur, like :
			V 0008|0000 lg :  x(e000fffe) 3758161918 [UL]
			but the parsing goes on, successfully.

			To be fixed !
