TIFF Tag VersionYear
Used in the TIFF-FX standard, denotes the year of the standard specified by the FaxProfile field.
The year is encoded as 4 characters, e.g. '1997'. The tag is used in lossy and lossless color modes.
The tag is described to be primarly used inside a GlobalParameters IFD, although the specification says that 'each field in the GlobalParametersIFD is a TIFF field that is legal in any IFD'.
