BTW, how do you plan to use that m_bFireEvent data member to decide to
skip or fire events in OPropertySetHelper::fire() ?  The method that
needs to be influenced by that boolean is still in the
OPropertySetHelper.

Actually, if this becomes problematic we probably *could* move this
boolean into OPropertySetHelper::Impl* m_pReserved.  That member is a
protected member, so the derived class should have access to it.

The problem of m_bFireEvent is solved, but I don't know what to do
with queryInterface; since it is not virtual, I cannot override it in
OPropertySetHelper2. The best I could come up with is something like (in
OPropertySetHelper):

Any OPropertySetHelper::queryInterface( const ::com::sun::star::uno::Type & rType )
    throw (RuntimeException)
{
    if ( rType == ::com::sun::star::beans::XPropertySetOption::static_type() )
    {
        XPropertySetOption * tmp = dynamic_cast< XPropertySetOption * >( this );
        if ( tmp )
           return Any( &tmp, rType );
        else
           return Any();
    }
   else
        return ::cppu::queryInterface(
            rType,
            static_cast< XPropertySet * >( this ),
            static_cast< XMultiPropertySet * >( this ),
            static_cast< XFastPropertySet * >( this ) )
}

But that is very ugly, since OPropertySetHelper has to know about
*all* the interfaces implemented by its derivatives!

Any better idea?
