Why are RSA model merge conflicts caused by broken cross-file references, difficult to resolve?

A.
RSA only utilizes UNC pathnames to reference other model files.

B.
RSA must maintain a reference model location registry for all models in a workspace.

C.
RSA manages cross-file references in the Eclipse preferences, which may not be consistent
between users.

D.
Cross-file references rely on filenames in the host file system that can be modified outside of
the Eclipse environment.
