i have the same problem. Even if i unlink all the xref's, can't delete the x-ref layers.
when the x-ref where "detached" we choose not to kept the x-ref attributes.....

thank you for your answers which confirms the impossibility of erasing these xref layers.
So for me it's a bug.
I am in phase synthesis on an important project, I tested many solutions, xref, external drawing, none give whole satisfaction, damage.
Stress wrote: Try reattaching the Xref file.... then detach it using Xref manager. The layers wil be gone.
that's the key to it: x-ref layers can only be deleted using the x-ref manager to detach the x-ref itself. otherwise they will sit in the file as locked orphan layers. it was an oversight on graphisoft's part that the new x-ref category of layer does not show in the attribute manager.
