public string BulkDataUri { get; set; }
The bulk data URI that is about to be written.
If BulkDataUri is passed to SaveXml, a dummy URI is generated for each binary data element that is about to be written, and is returned in BulkDataUri. This can be changed to a custom URI by setting the BulkDataUri to the desired URI.
This example will load a sample DICOM data set, then save it in the Native DICOM Model XML format specified in PS3.19.A.1 of the DICOM specification, changing each URI to a custom URI.
