 - Provides good auto-complete in IDEs.
 - Allows using a switch case by type to address different application flows.
 - Allows restricting communication to specific types.
+- Allow access to identifier details and use them to call other APIs (such as the Microsoft Graph API) to provide a rich experience for communication participants.
 
 On top of this, the *CommunicationIdentifier* and the derived types (`MicrosoftTeamsUserIdentifier`, `PhoneNumberIdentifier`, etc.) can be converted to its string representation (Raw ID) and restored from the string, making the following scenarios easier to implement:
-- Extract identifier details from Raw IDs and use them to call other APIs (such as the Microsoft Graph API) to provide a rich experience for communication participants.
 - Store identifiers in a database and use them as keys.
 - Use identifiers as keys in dictionaries.
 - Implement intuitive REST CRUD APIs by using identifiers as key in REST API paths, instead of having to rely on POST payloads.
