If it is a pure DUCET collation, will it be strength=tertiary and
alternate=shifted, or strength=quaternary and alternate=shifted?

I forgot the effect on primary when set to shifted. Shifted will take
affect regardless strength being 3 or 4.

Got the primary part. Thanks.

Will strength be 3 or 4 in this case, assuming it is a pure DUCET collation?

Will check it out.
