A keyref's refer must name a key or unique constraint. A refer pointing at a non-existent constraint was accepted. keyrefReferErrors collects all key/unique names and all keyref refers across the document (so a forward refer, textually before its key, is handled), then flags any refer with no matching name. Matched by local name, like the rest of the compiler. Skipped when the document declares import/include/redefine, whose externals the default compile does not load. XSTS: invalid schemas accepted 891 to 884 (-7); valid schemas rejected held at 72; instance buckets unchanged.
