Is this a standard type that just happens to have multiple filename extensions associated with it (like .jpg and .jpeg for JPEG files)? If so, there might be a UTI for that type, which you can just register for instead of registering for the filename extension directly.
If the type has no existing UTI (for example, if it's a type specific to your app), you can define your own UTI for it, and list the file extensions it uses in the UTI definition.
