Property entryRelationship : List(IcdaEntryRelationship); (Read/Write)
CDA has identified and modeled various link and reference scenarios. These scenarios enable CDA entries to be semantically linked to entries that exist within the same document (by traversing the entryRelationship class) or to objects external to it (by traversing the reference class).
NOTE: The CDA specification permits any CDA entry to relate to any CDA entry using any of the following relationship types. In many cases, this would result in nonsensical relationships. The following table is a guideline for reasonable relationships between CDA entries, and is not a conformance constraint.
