If I wanted to burn in an annotation to a Digital X-Ray because a PACS
system does not support GSPS objects; I think I should:
1) Create a new SOP Instance UID,
2)Create the Source Image Sequence and reference the original image
3) Add the the Derivation Description element to the DICOM header
4) Add the the Derivation Code Sequence to the header, but here's the
question: I don't see a code in chapter 16, the Content Mapping
Resource, to use for "Burned in Annotation"

Any thoughts?
