Configuration Option配置選項

• The Configuration Option transports additional attributes of entries in the Service Discovery messages. Between 0 and n configuration items can be transported using the Configuration Option. These configuration items can include for example the name of the host or the Service.
  Configuration Option傳輸Service Discovery 報文中entries之外的其他屬性。 可以使用配置選項傳輸0到n個配置項目。 這些配置項目可以包括,例如,主機或服務的名稱。

• Receiving a config_item_string without an “=” sign shall be interpreted as key present without value.
  接收不帶“=”符號的config_item_string應被解讀為沒有值的鍵
• Multiple config_item_string with the same key in a single configuration option shall be supported.
  應支持在單個配置選項中使用相同鍵的多個config_item_string
• If SdInstanceHostname exists, a key “hostname” with the value set to the string of this configuration item shall be added to the Configuration Option.
  如果SdInstanceHostname存在，則應在配置選項中添加一個鍵值為“主機名”的值，該值為該配置項的字符串
• Services exist, that are not identified by a unique 16 Bit Service ID but a unique value of the key otherserv. These services use the Service ID 0xFFFE and must always carry a configuration option with an otherserv record. ECUs receiving an entry with Service ID 0xFFFE shall use the configuration option and the otherserv record within in order to identify the relevant Service or Eventgroup configuration item. This means that two Service Instance with the same Service ID and Service Instance ID may exist as long as their otherserv record is different.
  有一些服務，它們不是由唯一的16位服務ID標識的，而是由鍵值otherserv的唯一值確定的。這些服務使用服務ID 0xFFFE，并且必須始終攜帶一個otherserv記錄的configuration option。接收具有服務ID 0xFFFE的entry的ECU應使用configuration option以及含在其中的otherserv記錄來識別相關的服務或事件組配置。這意味著具有相同服務ID和服務實例ID的兩個服務實例可以存在，只要其他otherserv記錄不同
• The configuration option shall be built based on configuration parameters mentioned in SWS_SD_00292.
  配置選項應根據SWS_SD_00292中提及的配置參數進行構建。
