nInstanceNumber	Pointer to a character string that contains the "Instance Number (0020,0013) element. Can be NULL.
pContentDate	Pointer to a VALUEDATE structure that contains the "Content Date" (0008:0023) element. Can be NULL.
pContentTime	Pointer to a VALUETIME structure that contains the "Content Time" (0008,0033) element. Can be NULL.
pAcquisitionDateTime	Pointer to a VALUEDATETIME structure that contains the "Acquisition DateTime" (0008:002A) element. Can be NULL.
pszBurnedInAnnotation	Pointer to a character string that contains the "Burned In Annotation" (0028:0301) element. Possible values are: "YES" "NO" Can be NULL.
pszDocumentTitle	Pointer to a character string that contains the "Burned In Annotation" (0028:0301) element. Can be NULL.
pszVerificationFlag	Pointer to a character string that contains the "Verification Flag" (0040:A493) element. Can be NULL.

pszListOfMIMETypes	Pointer to a character string that contains the "List of MIME Types" (0042:0014) element. Can be NULL.
nListOfMIMETypesCount	Unsigned integer contains the total number of null terminated strings that the pszListOfMIMETypes points to.

Comments

The members of this structure represent the set of attributes contained in the "Encapsulated Document Module Attributes". The Encapsulated Information Object Definition (IOD) describes either a

PDF document
CDA document

That has been encapsulated within a DICOM information object.

For more information, refer to Part 3 of the DICOM standard.

The pszMIMETypeOfEncapsulatedDocument field is ignored when calling the LDicomDS::SetEncapsulatedDocument function. The contents of the uType member determine the contents of the "MIME Type of Encapsulated Document" (0042:0012) element.

The pszListOfMIMETypes points to a string buffer that can contain zero or more null-terminated strings. The nListOfMIMETypesCount member contains the count of null-terminated strings. For example, the illustration below shows a character string, containing three strings separated by the 0 delimiter.

Any of the members of the structure that are pointers can be NULL. When calling the LDicomDS::SetEncapsulatedDocument function, NULL members will be ignored and the corresponding elements will not be inserted into the DICOM data set. When calling the LDicomDS::GetEncapsulatedDocument function, a member with a NULL value means that the corresponding DICOM element was not present in the DICOM data set.
