 ### Aliases
 
-The actor can have a convenient identifier and a descriptive label. Aliases can be defined in two ways: using external syntax with the `as` keyword, or inline within the configuration object.

     J->>A: Great!
 ```
 
-The external alias syntax also works with participant stereotype configurations, allowing you to combine type specification with aliases:
-
-```mermaid-example
-sequenceDiagram
-    participant API@{ "type": "boundary" } as Public API
-    actor DB@{ "type": "database" } as User Database
-    participant Svc@{ "type": "control" } as Auth Service

-    actor DB@{ "type": "database" } as User Database
-    participant Svc@{ "type": "control" } as Auth Service
-    API->>Svc: Authenticate
-    Svc->>DB: Query user
-    DB-->>Svc: User data
-    Svc-->>API: Token
-```
-
-#### Inline Alias Syntax
-
-Alternatively, you can define an alias directly inside the configuration object using the `"alias"` field. This works with both `participant` and `actor` keywords:
-
-```mermaid-example
-sequenceDiagram
-    participant API@{ "type": "boundary", "alias": "Public API" }
-    participant Auth@{ "type": "control", "alias": "Auth Service" }
-    participant DB@{ "type": "database", "alias": "User Database" }

-    Auth-->>API: Access token

-```mermaid
-sequenceDiagram
-    participant API@{ "type": "boundary", "alias": "Public API" }
-    participant Auth@{ "type": "control", "alias": "Auth Service" }
-    participant DB@{ "type": "database", "alias": "User Database" }
-    API->>Auth: Login request
-    Auth->>DB: Query user
-    DB-->>Auth: User data
-    Auth-->>API: Access token
-```
-
-#### Alias Precedence
-
-When both inline alias (in the configuration object) and external alias (using `as` keyword) are provided, the **external alias takes precedence**:
-
-```mermaid-example
-sequenceDiagram
-    participant API@{ "type": "boundary", "alias": "Internal Name" } as External Name
-    participant DB@{ "type": "database", "alias": "Internal DB" } as External DB
-    API->>DB: Query
-    DB-->>API: Result
-```
-
-```mermaid

-    participant API@{ "type": "boundary", "alias": "Internal Name" } as External Name
-    participant DB@{ "type": "database", "alias": "Internal DB" } as External DB
-    API->>DB: Query
-    DB-->>API: Result
-```
-
-In the example above, "External Name" and "External DB" will be displayed, not "Internal Name" and "Internal DB".

 ### Actor Creation and Destruction (v10.3.0+)
 
 It is possible to create and destroy actors by messages. To do so, add a create or destroy directive before the message.
