Pretty.  John's Suggestion is a step in the right direction.

However, it still fails the following "non-namespace" edge case...

    { not-specified, "html", "p" } == { not-specified, "html", "p" }
and { not-specified, ""    , "p" } != { not-specified, "html", "p" }
  
Let's repair...

  class QName {
    public:
      boolean isURI()      const;
      wstring qualifier()  const;  
      wstring local()      const;
      bool operator== (const QName &rhs) const;
  };

Where, in the not-specified cases, isURI() returns "false", 
and qualifier() returns the prefix.  And, in the specified
cases, isURI() returns "true" and qualifier() returns the URI.
