Comment 29 “The video elementary stream SHALL contain only spatial samples intended for presentation after SPS cropping parameters are applied in the decoder. The Clean Aperture box SHOULD NOT be present.”

“spatial samples intended for presentation after SPS cropping parameters”. Examples in appendix.

"Reviewed and still needs edits" leaves the editors with no idea what's wrong or how to fix it

Resolved in the CD. The text was revised to remove normative requirements on the content in the elementary stream ("SHALL contain only samples intended for presentation"), and changed to make functional statements about cropping, etc. specified by referenced codec and container normative references. That clarifies which samples are presented so authors can infer how to encode samples intended for presentation, but does not create an untestable requirement on content.
