MEMBER_OF the value is constrained to be equal to one of the specified values
NOT_MEMBER_OF the value is constrained to be not equal to any of the specified values
MEMBER_OF_CID the value is constrained to be equal to a member of the specified CID
UNCONSTRAINED the value of the Selector Attribute (0072,0026) is not constrained
For MEMBER_OF_CID, Constraint Value Sequence (0082,0034) shall contain a single Selector UI Value (0072,007F) , containing a Context Group UID (see PS 3.6, Table A-3. Context Group UID Values).
RANGE_INCL,RANGE_EXCL,GREATER_OR_EQUAL,LESS_OR_EQUAL,GREATER_THANorLESS_THANshallonlybespecified if the Selector Attribute (0072,0026) is AS, DA, DS, DT, FD, FL, IS, SL, SS, TM, UL or US.
See Section C.2.2.2 in PS3.4 for further guidance on value comparison.
Note
MEMBER_OF with a single Item in the Constraint Value Sequence (0082,0034) is valid and is equivalent to EQUAL.
10.25.1.1 Multi-valued Attribute Constraints
If the Attribute referenced by the Selector Attribute (0072,0026) has a value multiplicity of greater than 1 and the value of Selector Value Number (0072,0028) is 0, all values in the selected Attribute shall be compared to the single specified value. The constraint is violated if any of the multiple values do not satisfy the comparison.
10.25.2 Constraint Violation Significance
The violation of some constraints may be more significant than others. Constraint Violation Significance (0082,0036) differentiates three levels of signficance.
Specific behaviors associated with each level may be defined by the SOP Class or may be left to implementations. For example, vi- olation of a constraint with a significance of FAILURE might require operator intervention, special auditing or rejection of the target instance being evaluated; violation of a constraint with a significance of WARNING might require the operator be notified or a warning message be logged; violation of a constraint with a significance of INFORMATIVE might require an informational message be logged, or nothing at all if the constraint represents a preference not a signficant concern.
Note
Violation of a constraint does not imply that the Selector Attribute value is non-conformant to the Standard or is not clinically appropriate.

10.27 Reference Location Macro
This Macro allows a reference location in the context of a Patient or scan to be identified and described. E.g., the Macro may describe an anatomically defined location along the axis of a CT scan to prescribe the extent of a scan or reconstruction. The location might be internal to the Patient (and appear on a localizer image) or might be an external landmark (on which a laser is aligned).
