Existing Wording: Servers SHOULD return an ETag header with the versionId and a Content-Location header with the response which is the full version specific url (see vread below) and a Last-Modified header.

Proposed Wording: Servers SHOULD return an ETag header with the versionId and a Content-Location header with the response which is the full version specific url (see vread below) and a Last-Modified header. If servers do not support full versioning, the content-location header SHOULD be populated with the logical ID URL.

Comment:

Provide additional clarification on behavior when versioning is not supported
