I would say use the same name as that way, cherrypy give you a list.
Then write a custom schema/validator that validate the list form or use
some helper programs to loop through it against a simple validator.
I still think validation should not be a feature provided by the
framework and this feeling grows stronger as my apps evolve. For simple
CRUD like page, it may work(even that is not a given) but anything
involves some process logic and user friendliness, the framework based
validation can be thrown out.
