The C-FIND response shall not contain Attributes that were not in the request or specified in this section.
An Identifier in a C-FIND response shall contain:
Key Attributes with values corresponding to Key Attributes contained in the Identifier of the request.
Content Template Sequence (0040,A504), which shall include a single sequence item containing the Template Identifier (0040,DB00) and Mapping Resource (0008,0105) attributes, to identify the template structure used in the C-FIND response. The values shall be the same as specified in the Request Identifier.
Conditionally, the Attribute Specific Character Set (0008,0005). This Attribute shall be included if expanded or replacement character sets may be used in any of the Attributes in the Response Identifier. It shall not be included otherwise. The C-FIND SCP is not required to return responses in the Specific Character Set requested by the SCU if that character set is not supported by the SCP. The SCP may return responses with a different Specific Character Set.
