A QDM attribute provides specific detail about a QDM datatype.
An attribute that indicates one QDM data element fulfills the expectations of another QDM data element.
See Section 5.8 for examples for using relatedTo.
Note: QDM 5.6 relatedTo attribute is consistent with the FHIR element basedOn which is available for many FHIR resources addressed by the QDM datatypes added in the QDM 5.6 version. These QDM additions allow evaluation and testing during a period of FHIR transition specifically to relate actions with orders that generate them. However, measure developers should carefully determine feasibility for each use case when using the relatedTo attribute.
