PS 3.5 - 8.2.15 JPEG XL Image Compression

[Mathieu Malaterre]

Dear JPEG-XL gurus,

I am reading § 3.5 - 8.2.15 JPEG XL Image Compression (*), and I am suprised to see there is no note about the JPEG-XL header (the container) vs the JPEG-XL codestream. 

Could someone with more knowledge than me confirms:

1. JPEG-XL header ( ISO/IEC 18181-2) *must* be stripped before insertion in DICOM P10,

2. JPEG-XL naked codestream ( ISO/IEC 18181-1 ) must be /extra/-naked so as to remove both the color information and/or the orientation since they may conflict (redundant) with the actual DICOM header.

Thank you

-M
