/* The following NetLabel payloads are supported by the CALIPSO subsystem.
*
* o ADD:
* Sent by an application to add a new DOI mapping table.
*
* Required attributes:
*
* NLBL_CALIPSO_A_DOI
* NLBL_CALIPSO_A_MTYPE
*
* If using CALIPSO_MAP_PASS no additional attributes are required.
*
* o REMOVE:
* Sent by an application to remove a specific DOI mapping table from the
* CALIPSO system.
*
* Required attributes:
*
* NLBL_CALIPSO_A_DOI
*
* o LIST:
* Sent by an application to list the details of a DOI definition. On
* success the kernel should send a response using the following format.
*
* Required attributes:
*
* NLBL_CALIPSO_A_DOI
*
* The valid response message format depends on the type of the DOI mapping,
* the defined formats are shown below.
*
* Required attributes:
*
* NLBL_CALIPSO_A_MTYPE
*
* If using CALIPSO_MAP_PASS no additional attributes are required.
*
* o LISTALL:
* This message is sent by an application to list the valid DOIs on the
* system. When sent by an application there is no payload and the
* NLM_F_DUMP flag should be set. The kernel should respond with a series of
* the following messages.
*
* Required attributes:
*
* NLBL_CALIPSO_A_DOI
