Dear DICOM experts,and is a container item.
I am not 100% sure, but this appears to be a bug in the DICOM Standard.
We are implementing the Performed Imaging Agent Administration SR (PS3.3, A.35.20 and PS2.16, TID 11020).
Table A.188.8.131.52.3 describes the content item relationship constraints for this IOD. As defined by this table, the relationship HAS OBS CONTEXT is not allowed to relate a CONTAINER as a child of a parent CONTAINER.
However, the root template (TID 11020) includes TID 1002 with relationship type HAS OBS CONTEXT and nesting level (NL) 0, which in turn includes TID 1004 (Device Observer Context) with NL 0. Row 10 in TID 1004 inherits the relationship (HAS OBS CONTEXT)
It this some misconception on my end? Or is this really an inconsistency?items), but it would also allow to convey that the templates TID 1002, 1003 and 1004 are used.
By the way: I wonder why the creators of the standard have chosen to not encapsulate the observer context in a container. Not only would this make it more clear which attributes belong to which observer (and drop the "significant" order of content
Thank you very much for your guidance,
