The operation-specific +classes are all derived from the *SdncOperation* class, which is, itself, derived from +*HttpOperation*. Each operation class implements its own *makeRequest()* method to +construct a request appropriate to the operation. + + +Request +####### + +A number of nested structures are populated within the request. The following table +lists the contents of some of the fields that appear within these structures. + ++----------------------------------+---------+----------------------------------------------------------------------+ +| Field Name | Type | Description | ++----------------------------------+---------+----------------------------------------------------------------------+ ++----------------------------------+---------+----------------------------------------------------------------------+ +| top level: | | | ++----------------------------------+---------+----------------------------------------------------------------------+ +| *requestId* | string | Inserted by Policy.
