C&K has now confirmed their agreement to the modifications to DCR915 in new revision of 3401/085 Draft 3D (attached) (ref email dated 08/09/2015).
The modifications section of DCR915 shall be amended as follows:

Modifications:
1. As agreed with C&K, the original DCR attachment detailing the proposed changes is replaced by two new attachments:
i) DCR915 attachment - 3401085 issue 3D (Markedup).docx

ii) 3401085 issue 3D for publishing.docx
The proposed new revision specification (with all proposed changes agreed with C&K, implemented).
Note: The new revision 3401/085 Draft 3D implements the same basic changes to the specification as originally proposed by C&K in DCR915 but fixes various technical and editorial issues with the original DCR attachment; see 2. Below for details.
