Explicit-VR transfer syntax limits the value multiplicity of DICOM data elements with decimal string (DS) value representation

The Advanced Technology QA Consortium (ATC) has identified a problem in the encoding of DICOM RT Dose objects when these objects are converted from Implicit-VR (Little-Endian) transfer syntax to an Explicit-VR transfer syntax. There exist data elements, which can be represented in Implicit-VR Little-Endian transfer syntax but that cannot be represented in Explicit-VR Little-Endian transfer syntax.
