In this example, the client would handle updating the document itself. Behavior like this should however be triggered by Brackets in a central place to be extensible and possibly adjustable by the user. This requires the client definition to declare support for such operations in a structured manner.
This client would only support "reloading" by calling client.open again. For a more elaborate updating behavior, clients would need to declare support for such operations in a structured manner.
