Mapping from (not specified) to (not specified)

Group 1 Mapping from `urn:ihe:iti:2007:AssociationType` to DocumentRelationshipType

Source Code | Relationship | Target Code | Comment
RPLC | is equal to | replaces |
XFRM | is equal to | transforms |
APND | is equal to | appends |
XFRM_RPLC | narrower | replaces | An XDS Transform Replacement is both a document that replaces and transforms. The mapping here indicates Replace as that is the most specific change.
signs | is equal to | signs |
IsSnapshotOf | maps loosely to | transforms | An XDS IsSnapshotOf is a new instance of what is defined in the parent DocumentEntry (DocumentReference), thus it is a transform in a manner, but is not exactly a transform of the parent document.
