significance of AFX_CODEJOCK_PRIVATE

I've just inherited a fairly large body of MFC code that uses Codejock. I've noticed that the code refers to types (such asCXTPPropExchangeEnumeratorPtr) and methods (such as CXTPPropExchangeXmlNode::PreformatString) that are in an AFX_CODEJOCK_PRIVATE block. (The former of these is used in the examples in the documentatin, which muddies the waters yet further.)

Is such code intended to be called, or is it best avoided as an internal detail?

Many thanks

Without wishing to speak ill of my predecessor, neither can I at the moment. The code is below if that helps.

In general, should the items declared in such PRIVATE blocks be avoided? In which case, is std::auto_ptr<CXTPPropExchangeEnumerator> to be preferred over CXTPPropExchangeEnumeratorPtr?

void SomeClass::LoadXMLString(CXTPPropExchange* pPX, LPCTSTR pszPropName, CString& strValue)
{
#ifdef _UNICODE
    PX_String(pPX, pszPropName, strValue);
#else

    BSTR bstrValue = 0;
    PX_Bstr(pPX, pszPropName, bstrValue, 0);

    ASSERT(!bstrValue || wcslen(bstrValue) < 1024);

    if (bstrValue)
    {
        WideCharToMultiByte(0, 0, bstrValue, -1, strValue.GetBuffer(1024), 1024, 0, 0);
        strValue.ReleaseBuffer();
        SysFreeString(bstrValue);
    }
#endif
    CXTPPropExchangeXMLNode::PreformatString(strValue, FALSE);
}
