| forEvent | Defines the event for which this execution should be performed. It gives user the flexibility to define executions for each event. A valid event value must be given to this attribute. | String | N/A |
| Mandatory | promote/demote/publish - When this event is invoked, the life cycle's state changes from its current state to the target state which is defined in the "target" attribute of the <transition> element. | ||
| class | Defines the class that needs to be executed at runtime, when the user invokes the corresponding event within a given state. This class consists of business logic to be executed and facilitates environment changes during state transitions. A user must give the full, qualified name of a class that implements the | String | N/A | Mandatory | org.wso2.carbon.governance.registry.extensions. | Mandatory | The class named "org.wso2.carbon.governance .registry.extensions.executors.ServiceVersionExecutor" does provide the necessary business logic for the complete default lifecycle configuration model. |

| Description | The parameter elements incorporate the transition of the underlying resource by changing the environment during the state transition by providing the necessary arguments for the methods defined on the | Mandatory/Optional | in the business class which is declared by the class attribute within the <execution> element. The value of the name attribute can be given any name, but it has to be referred by the given name at the back end class defined within the <execution> element. If we omit the <parameter> element under the <execution> element during the state transition, the underlying resource does not move its environment(its storage path). |

| name | The 'name' attribute is referred by the business logic defined in the 'class' attribute of the <execution> element. | String | N/A |
| Mandatory | User should define a name for the given name attribute of the <parameter> element. It does not have any default values. Parameter will be referred later on by its name. | |||||||
| value | The 'value' attribute is used to compute the parameter's logic. | String | N/A | N/A | Mandatory | Since the artifacts are to be governed, the current and target environment have to start with "/_system/governance". In other words, the artifacts that are governed must be stored under "/_system/governance/" directory at any state transition. | value | The 'value' attribute is used to compute the parameter's logic. | String | N/A | N/A | Mandatory | value of the media types are predefined. Those values can't be changed. |
