Currently, when executing norsu rest endpoint for multi field and composite field with $type: deliveryEndpoint_v2, we can see metadata for nested content.

Step to reproduce: 

• Either you use https://git.magnolia-cms.com/projects/CLOUD/repos/norsu/browse/magnolia-demo-app/src/main/resources/demo-app/apps/content-app.yaml#166 or below simple content-app below: content-app.yamlto create multi field and composite field should be ok.
• Then execute the rest norsu endpoint
• See metadata for nested content:

From czimmermann expectation: Do not expect to see metadata for nested content like composite and multi field

Note: Compare to JCR. We still see @path for multi field and composite
