No, never heard of it before. > <https://www.alejandro-colomar.es/src/alx/linux/man-pages/man-pages.git/commit/?id=c59098078e6cab14e63941a4f2518bc1003a7d89> Scrolling through this, I see a Perl script that appears to process these XREF "macro calls" as well as cross references to page names spelled with leading and trailing '!' characters. Another telling point is that "XREF" is too long a macro name for AT&T-compatible *roffs. My guess is that this is one of many bespoke attempts at hyperlink anchor placement and linkage that people have grafted onto man(7) over the years, with `MR` in groff 1.23.0 being my attempt--though `MR` will only achieve its full flower once we get Deri's changes or some workalike equivalent landed, so that a compilation of man(7) (and mdoc(7)) pages can have "local" (intra-document) links without relying on a man(1) implementation to resolve "man:foo(1)" URLs.
