cspvalidator.org unrecognised directive-name

[mimin28g]

for referrer-policy and reflected-xss it keeps on saying "unrecognised directive-name".
Is this syntax error or the database on your end doesn't include it ...

"referrer-policy" never existed as far as I know, but "referrer" did for a little while. However, these were removed from the spec (x, x) in 2015, so these really are syntax errors.

The error message should probably mention that these were removed rather than just giving the generic "unrecognized directive" error, though.
