Zahlman: umm ya you are right, but my derogratory tone towards it was quite tongue in cheek. At the time i did suspect i was probably aware of what the term referred to, i still wasn't sure what exactly it was, and a quick google didn't make the connection between the term and what I refer to it as, which is by relation 'has a'.

Though the by relation, 'has a', description is possibly not as correct a description in all cases as composition it suits for most cases.
