Which of the following statements is applicable to new typelists?

The statement that no suffix should be added to all new typecodes is applicable to new typelists. In Guidewire, when creating new typelists, it is standard practice to avoid adding any suffixes like _Ext to the new typecodes. This approach ensures consistency and clarity in the naming conventions used within the application.

When typelists are defined, adhering to naming conventions without additional suffixes simplifies the integration and referencing of these types throughout the system. Each new typecode should be straightforward and recognizable without the need for modifiers that could potentially confuse developers or users interacting with the data.

Other statements, such as requiring the _Ext suffix or limiting the number of typelists per entity, do not align with the typical practices surrounding the creation or management of typelists in the Guidewire platform. This helps underline the importance of direct and uncomplicated naming in the context of typecodes.
