What does the .tti file represent in Typelist file types?

The .tti file in Guidewire's Typelist file types stands for Typelist Type Info. These files are used to define the characteristics and metadata for types within a typelist, which is an important component of the data model in Guidewire applications. The .tti file contains details such as the display names, descriptions, and values associated with the typelist types. This information is crucial for the application’s functionality, as it allows developers and users to interact with these types in a meaningful way.

In the context of the other options, "Typelist Internal Extension" and "Typelist Type Extension" do not accurately describe the purpose or content of the .tti file. These terms do not reflect the standard naming conventions found in Guidewire. Additionally, the option "None of the above" does not apply since "Typelist Type Info" accurately describes the .tti file. Thus, identifying it as Typelist Type Info is essential for understanding how these files function within the Guidewire ecosystem.
