Remarks

Only certain properties support append operations. An attempt to append to a property that does not support appending will result in an error.

For update operations, only one property can be modified within a single request. That single property must be referenced in the Path element. The Item element in the derived classes can then only hold a single property that is in agreement with the single Path element.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
