Hi Rob,

Thanks for assisting with the review and suggesting an improved method
in patch [2/16] and here for bounding related item quantites.

I have a question regarding the current item description. It seems to
imply a specific order. If the order of the description is different
for any reason, should it be fully re-listed under 'allOf'?

Sincerely,
Moudy
