Exported Type Declarations
You can declare custom UTIs by providing an exported type declaration in your Info.plist property list. These type specifications mirror the ones in Figure 16-7, which is used for declaring document type support. Figure 16-7 shows a type declaration for JPEG images.

Again, you see each of the keys that can be retrieved via the UTTypeCopyDeclaration()function. Here, those items are specified to the system as a preliminary declaration. You can easily adapt this template to create your own custom file types and associated UTIs as needed. The most common reason for declaring a new type is to introduce support for file formats supported on other platforms.
