You surprise me. I had always assumed that Xref was only meaningful for a
particular server and the clients that used it, and that if ever it
received an already-present Xref (from whatever source) it would simply
discard it and substitute its own. But if it is as you say, then I suppose
that MUST has to remain (otherwise, SHOULD would have sufficed).

Sure. If we agree on the effects we want to achieve, then I am due for a
careful read through the whole document to see what final inconsistencies
might be lurking there,
