DRMVerify function

[The AD RMS SDK leveraging functionality exposed by the client in Msdrm.dll is available for use in Windows Server 2008, Windows Vista, Windows Server 2008 R2, Windows 7, Windows Server 2012, and Windows 8. It may be altered or unavailable in subsequent versions. Instead, use Active Directory Rights Management Services SDK 2.0, which leverages functionality exposed by the client in Msipc.dll.]

[The DRMVerify function is no longer supported and returns E_NOTIMPL.]

For Rights Management Services 1.0, the DRMVerify function verifies data signed with DRMAttest.
