Minimum Rules to Include

TIFF Validation can produce an image TIFF variance indicator according to ANS X9.100-181 Annex A. It does this by examining actual values in the output. Therefore, to enable producing image TIFF variance indicators, TIFF Validation must generate certain minimum output by including the tag tests shown below.
