The method createSlot in the interface LifeCycleManager takes 3 parameters; its signatures are as follows:

The CentraSite implementation accepts any value of type String, or a null reference, for the third parameter, slotType. This parameter is stored with the slot, but it is not interpreted in any way. Note, however, that the JAXR standard does not indicate how this parameter should be interpreted; it might, for example, be interpreted as indicating the data type of the slot in some future implementation. We recommend specifying the slotType as an xs:string.
