| 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.

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 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. |
