Clarify priority of names above the rank of genus

[lmrodriguezr]

The SeqCode Registry currently determines priority under SeqCode exclusively based on the date of notification.

However, note:

Rule 23d The priority date of names of taxa of rank higher than genus proposed after 1 January 2022 is the same as the priority date of the corresponding type genus name. The priority date for names published before 1 January 2022 is the same as their priority under the ICNP.

Which conflicts with:

Rule 25 The time and date of validation is the time and date of completion of the registration in the SeqCode Registry.

Unless we explicitly make a distinction between time and date of validation and priority date

Also relevant:

Recommendation 28 The effective publication should be cited with the name of a previously proposed taxon. Correct citation of a name enables the date of publication, the description, and the circumscription of the taxon to be found. For names published under the SeqCode, the validly published name and date of valid publication should be determined from the SeqCode Registry.
