These are additional elements containing information to strengthen the authentication of the metering data beyond that offered by the Metering certificates specified in [MS-DRM]. This is used to ensure the source of the information is valid.

 </xs:complexType>

MID: Identifies the MID to associate with the metering certificate.

PUBLICKEY: Contains a base64-encoded ECC public key, in the PUBKEY format ([MS-DRM] section 2.2.1.6). The PUBKEY is the public portion of a public-private key pair in ECC1. Base64 encoding is performed as specified in [MS-DRM] section 2.2.1.1. This identifies the public key for the metering certificate, which is used for encrypting the Metering Protocol messages.
