Background and motivation

#1795, #2260, #2283 and #2328 all thought that subjectList.ContainEquivalentOf(expectedList) tries to find a subset in subjectList that is equivalent to expectedList.
What ContainEquivalentOf does is trying to find an element within subjectList that is equivalent to expectedList.

Is there some xml-documentation or website docs/examples that are missing, incorrect or could be improved to avoid these confusions?
