Remarks

The child elements of the MetadataKey element specify the metadata that the operating system uses to do the following:

Search the device metadata store for a device metadata package based on either a device's ModelID or HardwareID value. If more than one metadata packages match the device's Model or Hardware ID, the operating system also compares the Locale value within the metadata package to the current language setting on the user's computer.
Update the device metadata store with the device metadata package if a package has a more recent LastModifiedDate value than an existing package within the device metadata store.

The MetadataKey element must contain:

One instance of the Locale and LastModifiedDate elements.
One instance of either the HardwareIDList or ModelIDList elements. The MetadataKey element can contain one instance of both elements.

The MetadataKey element is required.
