#### C.23.4.2 Hanging Protocol Selector Attribute Value Macro

Table C.23.4-2 specifies the Attributes that identify the value(s) for a Data Element Tag that is used as a Selector Attribute (0072,0026) in the Image Set Selector Sequence (0072,0022) or Filter Operations Sequence (0072,0400).

###### C.23.4.2.1.1 Selector Attribute Value Matching

The value of Specific Character Set (0008,0005) in the Image and the Hanging Protocol Instance may differ and shall be taken into account for matching.

The value of Specific Character Set (0008,0005) may influence how matching of text Attributes is performed, in an implementation dependent manner. No requirements are specified for case sensitive or accent sensitive matching, or for ignoring padding.

###### C.23.4.2.1.2 Selector Code Sequence Value

The matching shall be performed on Coding Scheme Designator (0008,0102) and Code Value (0008,0100). Code Meaning (0008,0104) is required to be present, but shall be ignored for matching purposes. The matching is case sensitive, and leading and trailing spaces are not significant. The Coding Scheme Version (0008,0103) shall be ignored unless Coding Scheme Designator (0008,0102) is not sufficient to identify Code Value (0008,0100) unambiguously.
