    This file declares Vector Handoff Info PPI that describes an array of
    interrupt and/or exception vectors that are in use and need to persist.
  
    This is an optional PPI that may be produced by SEC. If present, it provides
    a description of the interrupt and/or exception vectors that were established
    in the SEC Phase and need to persist into PEI and DXE.
