Filtering is the way a request XML packet indicates to which objects to apply an operation. Parameters nested in the filter node are called filtering rule.
The filter node is presented by the PlanItemFilterType complex
plan_item.xsd). Its graphical representation is as follows:
- The all node is optional. It is used when the operation is applied to all custom options of service plans (additional services).
- The name node is optional. It specifies the additional service name .
