[Idngwg] recommendation #17

[Edmon]

A rough suggestion for updating #17:

17. TLD registries are recommended to explain in their registration policies, how additional constraints, if any, are applied on registrations to minimize Whole-Script Confusables as determined by Unicode Technical Standard #39: Unicode Security Mechanisms http://unicode.org/reports/tr39/tr39-1.html#Whole_Script_Confusables. Also see 18 (d) and Additional Note V.
