An issue has been identified in SMPTE RP 2057 (Text-Based Metadata Carriage in MXF), in which the Universal Label (UL) defined in Table 4 (byte 13 = 03h), used to identify text-based descriptive metadata, also has been used in deployed equipment to identify a different descriptive metadata scheme (AMWA AS-03).
