I appreciate this is probably a done deal by now, but I prefer:

class QName {
    wstring ns () const;           // http://www.w3c.org/1999/xhtml
    wstring name () const;         // p
    wstring nsPrefix () const;     // html
    wstring prefixedName () const; // html:p

    bool operator== (const QName &rhs) const;
                                   // ns & name both equal
    // Probably just a simple pointer to your internal data structures

void startElement (const QName &name, const AttributeList &atts)
throws SAXException;

You can also provide a specialisation for class std::less<QName>, and then
QNames become directly usable with the STL set/map classes.

Hiding the internals lets you use some cleverer comparison techniques, too,
so that, e.g.

    if (qn1 == qn2) ...

can happen faster than doing the various string comparisons.

N.B. the code above is phrased assuming the use of wstring for string data,
because I prefer it, but could readily be adapted to raw wchar_t*, or
SAXChar, or whatever comes out of the other debate)
