That has not been our practice up to now, eg in comparable cases in
discussions of GUC variables, only the first reference is xref-ified.
I think it could be kind of annoying to make every reference a link,
both for regular readers (the link decoration is too bold in most
browsers) and for users of screen-reader software.
There is a fair question as to how far apart two references should
be before we <xref> both of them. But I think that distance
does need to be more than zero, and probably more than one para.
