Enum: DICOMAttributeTypeEnum

Attribute requirement types defined in DICOM PS3.5 Section 7.4, which state whether an attribute must be present in a data set and whether it may have a zero-length value. Conformance checkers report missing Type 1 and Type 2 attributes as errors. These types also determine which de-identification action (D, Z or X) may be applied to an attribute.
