Hi Scott,

  This is correct that Curve Data have been removed, however only
*even* group are allowed. Def is in ps 3.5:

7.6 REPEATING GROUPS
...
Repeating Groups shall only be allowed in the even Groups
(6000-601E,eeee) and even Groups (5000-
501E,eeee) cases. In the future, Data Elements with VRs of SQ shall be
used to serve a similar purpose.
