All Resources that are part of a Release are contained in a <ResourceList> composite. This composite forces that all Resources are communicated in a specific order:

Of course, this order may not be the one that an artist has decided that the Resources should appear on his/her/their Release. The right – and only – place to communicate the sequencing of Resources is the <ResourceGroup> (which is part of the <ReleaseDetailsByTerritory> composite).

The sample on the right shows how this can be done. For the avoidance of doubt, the <ReleaseResourceReferenceList> cannot be used to sequence Resources.

The <ResourceGroup> can also be used to group Resources into the digital equivalent of "sides" and "disks" (e.g. for boxed sets).
