// These are the general "classifications" of driver errors, along with the
// default flags that will be applied the first time this is hit.
//
// ViMessageClassFailDriverInField -
//     Bugs in this class are severe enough that the driver should be
//     immediately removed from a running production machine.
//
// ViMessageClassFailDriverLogo -
//     Bugs of this class are severe enough for WHQL to deny a logo for the
//     failing whateverware.
//
// ViMessageClassFailDriverUnderDebugger -
//     Bugs of this class stop the machine only if it is running under a
//     kernel debugger.
//
// ViMessageClassDriverWarning -
//     Anything in this class will beep but continue without breaking in.
//
// ViMessageClassPostponedDriverIssue -
//     Anything in this class will merely print and continue.
//
// ViMessageClassCoreError -
//     Issue in a core component (kernel or hal)

Routine Description:

    This routine takes a failure ID and retrieves the text template and the

Arguments:

    MessageTable        - Message table to use.

    MessageID           - Failure code (doubles as bugcheck minor).

    AnsiDriverName      - Name of the driver that failed verification.

    BugCheckMajor       - Receives bugcheck major code if applicable.

    MessageClass        - Receives a pointer to a VFMESSAGE_CLASS structure
                          that contains information on how to handle the error.

    MessageTextTemplate - Receives a pointer to the text associated with the
                          failure code.

    TemplateFlags       - Receives address of the assertion's control field,
