## External Communication Elements

Element | Attributes | Support and Notes

`<send>` | Overall | Partial support — restricted to SCXML-to-SCXML communication
event | Full support
target | Full support "scxml" type — The value will be the session ID. "basichttp" type — The value will the URL of the receiving application. "fm" type — The value will be the namespace of the given functional module. For details see the Supported URI Schemes section. Note: This element by default puts the event in the external event queue. However, the special value '`_internal`' for the target attribute results in the event being placed in the internal event queue.
targettype | Limited support — Will only support the following: "scxml" for sending events between different SCXML documents "basichttp" for sending events to 3rd party applications. "fm" for sending events to functional modules.
