This type of set constructor should have a final argument which is a sample of the thing being constructed as in <set> <bvar><ci>i</ci></bvar> <bvar><ci>c</ci></bvar> <condition> <apply><eq/> <ci>c</ci> <apply><times/> <ci>i</ci> <cn>2.54</cn> </apply> </apply> </condition> <list><ci>i</ci><ci>c</ci></list> </set> They should be grouped in some way, for example, using a set, list or vector.
