I think it is instructive to look at Duchamp in this context. In a very clear sense, the transformative with regard to art lies in changing it's meaning. However, this can be a very subtle thing. And it may be that the subtlety is not realised or played out in the way the artist intends, or in the way that the viewer receives it. This could then boil down to a matter of quality, or strength. It is not even that simple. If Duchamp's early forays into 'readymades' had been slapped with lawsuits, we may never have had 'the fountain'.
