interface IMetaDataDispenser : IUnknown {
        
    HRESULT DefineScope (
        [in]  REFCLSID    rclsid,
        [in]  DWORD       dwCreateFlags,
        [in]  REFIID      riid, 
        [out] IUnknown    **ppIUnk
    );
        
    HRESULT OpenScope (
        [in]  LPCWSTR     szScope, 
                [in]  DWORD       dwOpenFlags, 
        [in]  REFIID      riid, 
                [out] IUnknown    **ppIUnk
    );
        
    HRESULT OpenScopeOnMemory (
        [in]  LPCVOID     pData, 
        [in]  ULONG       cbData, 
                [in]  DWORD       dwOpenFlags, 
        [in]  REFIID      riid, 
                [out] IUnknown    **ppIUnk
