I agree that rootElements is the simpler and preferred approach. Bringing
up the relationship approach in the discussion made me wonder if I was
missing something, and the element type is what I might be missing.
document
id: id0
namespace: foo
rootElements:
id1
id2
elements:
id: id1
type?: file?
What part of the element tells you that the element is a snippet or file or
package or sbom?
