Constants
created 2u created In a setter method: specifies that an object should be created. An error is returned if the object already exists.
In the return value of a setter method: indicates that an object has been created.
modified 4u modified In a setter method: specifies that an object should be modified
In the return value of a setter method: indicates that an object has been modified.
deleted 8u deleted In a setter method: specifies that an object should be deleted.
In the return value of a setter method: indicates that an object has been deleted.
DEFAULT 0 --- This type controls the life cycle of objects passed in the XML API.

When used in a setter method (such as configConfMo), the ModificationStatus specifies whether an object should be created, modified, deleted or removed.
In the return value of a setter method, the ModificationStatus indicates the actual operation that was performed. For example, the ModificationStatus is set to "created" if the object was created. The ModificationStatus is not set if the object was neither created, modified, deleted or removed.

When invoking a setter method, the ModificationStatus is optional:
If a setter method such as configConfMo is invoked and the ModificationStatus is not set, the system automatically determines if the object should be created or modified.
