The CachedLoadingType provides information about the Current Version, the Pending Version and the Fallback Version (if supported). Additionally, it allows upload and download of different versions of the software. The Cached-Loading option is described in 8.3.4.4.
The CachedLoadingType is illustrated in Figure 44 and formally defined in Table 71.

The FileTransfer Object is inherited from the PackageLoadingType. In this sub-type the Current version shall not be writable and the Pending version shall be writable (see SoftwareVersionFileType in 8.5.1).
The PendingVersion Object describes an already transferred new Software Package that is ready to be installed.
If there is no Software Package available, the values should be empty.
The optional FallbackVersion Object describes an alternate version on the device. This could be a factory default version or the version before the last update. Installing the Fallback Version may be used to revert to a reliable version of the software.
If a Fallback Version is supported by the device the object shall be available. If there is currently no Fallback Version on the device, the values should be empty.
With this Method the Client may check the specific update behavior for a specified software version. To identify the version the GetUpdateBehavior Method requires the ManufacturerUri, SoftwareRevision and PatchIdentifiers Properties of the SoftwareVersionType.
