// NOTE:

// 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.
