// The m_vValue in the CKeyRef may not be of the expected type, i.e., the parser
// cannot distinguish 16 bit integers from 32 bit integers if they fall within the
// legal subrange of a 16 bit value. Therefore, the parser only uses the following
// types for keys:
// VT_I4, VT_R8, VT_BSTR
// If the underlying type is different, the user of this parser must do appropriate
// type conversion.
