It should be an extensible list.

The registry is on the ICC website at
The metadata registry is in the dropdown list under the Resources tab at

After the values are agreed among you, provide a table with the information
fields shown in the metadata registry and Phil Green, the ICC Technical
Secretary, can add the items to the registry. Please send to me as well.

Best regards,
