/** The OMX_VERSIONTYPE union is used to specify the version for
    a structure or component.  For a component, the version is entirely
    specified by the component vendor.  Components doing the same function
    from different vendors may or may not have the same version.  For 
    structures, the version shall be set by the entity that allocates the
    structure.  For structures specified in the OMX 1.1 specification, the
    value of the version shall be set to 1.1.0.0 in all cases.  Access to the
    OMX_VERSIONTYPE can be by a single 32 bit access (e.g. by nVersion) or
    by accessing one of the structure elements to, for example, check only
    the Major revision.
