7.5.3 Sequence Inheritance

An encapsulated Data Set shall only include the Specific Character Set (0008,0005) Data Element if the Attribute Specific Character Set is defined in the IOD for that sequence of items.

Note

An encapsulated Data Set does not include the Specific Character Set Data Element unless the Specific Character Set Attribute is defined as part of the IOD for that sequence.

If an encapsulated Data Set includes the Specific Character Set Attribute, it shall apply only to the encapsulated Data Set. If the Attribute Specific Character Set is not explicitly included in an encapsulated Data Set, then the Specific Character Set Value of the encapsulating Data Set applies.
