The CRNP uses three types of XML-based messages. Use of these messages is described in the following table. These message types are described in more detail later in this chapter.
CRNP Message Type |
Description |
---|---|
SC_CALLBACK_REG |
This message takes four forms: ADD_CLIENT, REMOVE_CLIENT, ADD_EVENTS, and REMOVE_EVENTS. Each of these forms contains the following information:
ADD_CLIENT, ADD_EVENTS, and REMOVE_EVENTS also contain an unbounded list of event types. Each of these forms includes the following information:
Together, the event class and event subclass define a unique “event type.” The document type definition (DTD) from which the classes of SC_CALLBACK_REG are generated is SC_CALLBACK_REG. This DTD is described in more detail in Appendix F, Document Type Definitions for the CRNP. |
SC_REPLY |
This message contains the following information:
The DTD from which the classes of SC_REPLY are generated is SC_REPLY. This DTD is described in more detail in Appendix F, Document Type Definitions for the CRNP. |
SC_EVENT |
This message contains the following information:
The values in an SC_EVENT are not typed. The DTD from which the classes of SC_EVENT are generated is SC_EVENT. This DTD is described in more detail in Appendix F, Document Type Definitions for the CRNP. |
