    //      is fgPCDataElemId, then its a PCData node.  Else, it is zero.
    //
    //  fFirst
    //  fSecond
    //      The optional first and second nodes. The fType field indicates
    //      which of these are valid. The validaty constraints are:
    //
    //          Leaf = Neither valid
    //          ZeroOrOne, ZeroOrMore = First
    //          Choice, Sequence, All = First and Second
    //          Any* = Neither valid
    //
    //  fType
    //      The type of node. This controls how many of the child node fields
    //      are used.
    //
    //  fAdoptFirst
    //      Indicate if this ContentSpecNode adopts the fFirst, and is responsible
    //      for deleting it.
    //
    //  fAdoptSecond
    //      Indicate if this ContentSpecNode adopts the fSecond, and is responsible
    //      for deleting it.
    //
    //  fMinOccurs
    //      Indicate the minimum times that this node can occur
    //
    //  fMaxOccurs
    //      Indicate the maximum times that this node can occur
