  We study the properties of section conditions of the E7(7) exceptional field
theory from the perspective of superparticle model in N=8 D=4 superspace
enlarged by additional bosonic coordinates related to the central charge of the
maximal supersymmetry superalgebra. In particular, the superparticle model
suggests that only a part of the section conditions corresponding to generators
of SU(8) subgroup of E7(7) is independent, and we show that this part indeed
suffices to obtain the (classical counterpart of the) general solution of the
strong section condition.
