  Single crystal diffuse scattering is generally interpreted using correlation
parameters that describe probabilities for certain configurations on a local
scale. In this paper we present a novel interpretation of diffuse maxima using
a disordered superspace approach. In (D+d)-dimensional superspace two
modulation functions are disordered along the superspace axis $\vec{a}_{s,i}$
for i = 1,..,D, while the periodicity along the internal dimensions is
maintained. This simple approach allows the generation of diffuse maxima of any
width at any position in reciprocal space. The extinction rules that are
introduced by superspace symmetry are also fulfilled by the diffuse maxima from
structures generated using the disordered superspace approach. In this
manuscript we demonstrate the disordered superspace approach using a simple a
simple two-dimensional binary disordered system. The extension of the approach
to (3+D)-dimensional superspace is trivial. The treatment of displacement and
magnetic disorder in a similar approach is straight forward.
