1. Yong has added a comment to the discussion board:
https://confluence.ihtsdotools.org/display/USRG/Additional+Attributes+for+National+Drug+Extensions
This includes a proposed new MRCM for 30465011000036106 |Has container type (attribute)|. Yong has raised questions regarding the domain, range (especially with respect to specific physical object values), and cardinality (also consider multi-container products, subpacks, and the implications for classification).

2. The attributes list from Canada is also available on the discussion board. Additional relevant content can be found on this page:
