Here is what I mean by definitions. If one looks at the parton model proposed by Feynman (e.g. quark model) then we see the derivation of momentum distributions for different types of partons (quarks). We have to assume again that seeing a quark at some momentum carries uncertainty, so calualationclly we have to expand out the potential momentum states. In my mind this is a type of compositeness, even if it isn't defined as such from other points of view.
