Note
1.Tag (0040,A170) was defined as Observation Class with a VR of "CS" in the Frozen Draft version of Supplement 23 "Structured Reporting" (from November 20, 1997). Implementers of the Standard should be warned that old objects of the associated SOP Classes exist and that they use this VR instead of "SQ". In particular, when reading objects with Implicit VR Little Endian transfer syntax, this inconsistency might result in parsing errors if not handled appropriately.
2.The VR for Data Elements, Item (FFFE,E000), Item Delimitation Item (FFFE,E00D), and Sequence Delimitation Item (FFFE,E0DD) do not exist. See PS3.5 for explanation.
3.For some Data Elements, no Name or Keyword or VR or VM is specified; these are "placeholders" that are not assigned but will not be reused.
