An assert/report may reference <diagnostic> messages by id through its diagnostics= attribute; each referenced diagnostic is rendered (with the same value-of/name/let substitution) and appended to the finding for extra per-failure detail. <diagnostics> is collected schema-wide. Schema/pattern-level let, abstract patterns, and key()/document() remain. Part of #80
