|ref= - empty or missing: get names and date from whitelist defaults; override defaults from externally visible template parameters
|ref=harv - same as empty or missing
|ref={{SfnRef|name|name|name|name|year}} - assemble an anchor id from {{sfnref}} positional parameters
|ref={{Harvid|name|name|name|name|year}} - assemble an anchor id from {{harvid}} positional parameters
|ref=none - skip; do nothing because an anchor id intentionally suppressed; TODO: keep with a type code of '0'?
|ref=<text> - save param value because may match an anchor id override value in {{harv}} template |ref= parameter or {{harvc}} |id= parameter
