By examining the prevalence of EXIF markers in JPEG images, and to a lesser extent, we are requiring support for the EXIF 2.2 JPEG markers and TIFF tags as part of the XPS Specification. The new conformance rules are as follows:
Consumers MUST support JPEG images that contain the APP1 marker and interpret the EXIF color space correctly [M2.78].
EXIF IFD (tag 34665) as described in the EXIF specification. The EXIF color space MUST be interpreted correctly [M2.79].
