备注Remarks

只有某些属性支持 append 操作。Only certain properties support append operations. 如果尝试追加到不支持追加的属性,则会导致错误。An attempt to append to a property that does not support appending will result in an error.

对于更新操作,只能在单个请求中修改一个属性。For update operations, only one property can be modified within a single request. 必须在Path元素中引用该单个属性。That single property must be referenced in the Path element. 然后,派生类中的Item元素可以仅保留与单个Path元素一致的单个属性。The Item element in the derived classes can then only hold a single property that is in agreement with the single Path element.

备注

Path元素是抽象的。The Path element is abstract. 它必须由FieldURIIndexedFieldURIExtendedFieldURI元素替代。It must be substituted by the FieldURI, IndexedFieldURI, or ExtendedFieldURI element.
