Following up to my own post (and thanks to Steven Young for finding this for me :) - PWG 5101.1 does actually talk about a long dimension of 0 for roll sizes in sections 5.1 and 5.1.3.  Specifically, when the roll size is unknown or unbounded, a Printer should report a long dimension of 0 in the ready media.  If your roll printer keeps track of the remaining length then it should report the appropriate range instead of 0...

So, it looks like media-col-ready/media-size/y-dimension should have a syntax of integer(0:MAX)|rangeOfInteger(1:MAX) while all of the other x-dimension and y-dimension member attributes should be integer(1:MAX)|rangeOfInteger(1:MAX).

And of course I will make sure the updated test in 5100.7 mirrors the wording in 5101.1 and makes it explicitly clear for everyone.

Since the media-size-supported values have a range of 1:MAX then that is what the other media-size values should have as well.  And honestly I'm not sure what a media size of 0x0 would represent...

HP Inc. is also requesting that the definitions specify a lower bounds of 0 instead of 1 for the "x-dimension" and "y-dimension" members of "media-col-database" and "media-col-ready" to match the member definitions in the "media-col" Job Template attribute.
